Preparation and Dosing Considerations
Traditional PreparationTypically, the indigenous people of Peru boil 20-30 grams of Uncaria tomentosa inner bark in a liter of water for 30-60 minutes to prepare a tea. (If the tea is shredded, 30 minutes is sufficient.) This is then consumed throughout the day for several days to several months.
Infusion
Ten grams of dried Uncaria tomentosa inner bark can be boiled in one liter of water to produce a tea. Drinking 2-3 cups of this tea daily can be very beneficial for a person with immune system compromise for long-term use up to 3 months, 4 to 5 times a week only.
If you add lemon juice or vinegar to the decoction when simmering, you will extract more alkaloids and less tannins from the bark. Use about 1/2 teaspoon of lemon juice or vinegar per cup of water. Finely ground bark capsules are practically worthless.
Liquid Extract
Whole World Botanicals also offers Royal Cat’s Claw liquid extract. The usual therapeutic dosage of Uncaria tomentosa liquid extract is 1 to 4 ml per day. The liquid extract may be taken directly under the tongue or added to water or juice. It tastes good with chocolate!
Directions
Drink one-half cup of tea at least 15 minutes before eating or two hours after eating, 2-4 times daily or as directed by your healthcare practitioner. Do not take at bedtime if it interferes with your sleep. As with most herbs, it is advised to cycle on and off rather than to take it continuously. For example, 3 months on and one moth off or 4 days on and 3 days off (weekly).To prepare: Put 8 teaspoons of loose tea into 5 cups of boiling water. Reduce heat and simmer the tea in a pot without a lid for 30 minutes. Strain. Makes 4 cups of tea. It tastes best if taken hot or very cold. Ice cubes and stevia may be added. The tea may be stored in the refrigerator in a glass or plastic jar with a lid for up to one week.
For those with sensitive stomachs, add ½ teaspoon of lemon juice to each cup of water used in preparing the tea. This will bind up most of the tannic acid and make the tea less astringent.
Contraindications
Organ/Bone Marrow Transplant: Since Cat’s Claw activates and strengthens the immune system, its use is contraindicated before or following any organ or bone marrow transplant or skin graft.Anti-fertility: Cat’s Claw taken at a high dosage has been documented with anti-fertility properties and is contraindicated in persons seeking to get pregnant, but may not be considered as a reliable contraceptive.
Warning about Pharmaceutical Blood Thinners: Since Cat’s Claw contains chemical compounds which can reduce platelet aggregation and thin the blood, consult your physician if you are taking Coumadin® or other blood thinning drugs. Discontinue use one week to ten days prior to any major surgical procedure.
Warning about Low Blood Pressure: Since Cat’s Claw might lower your blood pressure, people with low blood pressure need to increase fluids and salt when taking Cat’s Claw more than once a day. Two alkaloids in Cat’s Claw have been documented to lower blood pressure. Individuals with low blood pressure or taking antihypertensive drugs should consult their physician and monitor their blood pressure levels while taking Cat’s Claw. Medications may need adjusting.
Keep away from children. Not to be used if you are pregnant or nursing.
Possible side effects
Stomach: Cat’s Claw requires sufficient stomach acid to help break down the tannins and alkaloids during digestion, and to aid in absorption. Avoid taking liquid extracts directly by mouth and dilute first in water or acidic juice. Smaller more frequent amounts may be taken by individuals with digestive issues.Tannic acid: If the tannic acid in Cat’s Claw is not well tolerated, try preparing Cat’s Claw tea with added lemon juice because it lowers the amount of tannic acid released from the Cat’s Claw bark.
Gastrointestinal Problems: Large dosages of Cat’s Claw (3–4 ml—approximately one teaspoon of liquid extract) may cause abdominal pain or gastrointestinal problems in some individuals. This is related to the tannin content. A small portion of people may experience diarrhea or loose stools, but this tends to be mild and dissipate with continued use. Discontinue use or reduce dosage if diarrhea persists longer than 3–4 days.
Drug Interactions
Due to its immunostimulant effects and the possible interference of Cat’s Claw it should not be used with medications intended to suppress the immune system, such as cyclosporine or other medications prescribed following an organ transplant.Preparation and Dosing Considerations

Cat’s Claw (Uña de Gato in Spanish) is the bark and root parts of a woody vine which grows in the Peruvian Amazon. Whole World Botanicals uses Uncaria tomentosa in its Royal Cat’s Claw because it is the most potent species of this plant and offers unique benefits listed below.Through scientific research, Cat’s Claw has been shown to
- Strengthen the immune system*
- Promote healthy inflammation response in auto-immune conditions, including lupus, asthma, arthritis, Crohn’s Disease, etc.*
- Promote a healthy CRP (C-reactive protein) in the blood – associated with plaque buildup in arteries*
- Increase cell death (apoptosis) of abnormal cells*
- Repair DNA of mutated cells*
- Promote healthy blood pressure (Note: Since Cat’s Claw might lower your blood pressure, people with low blood pressure need to increase fluids and salt when taking Cat’s Claw more than once a day.

What makes Royal Cat’s Claw royal?
Superior Potency Royal Cat’s Claw is a very potent 1:1 liquid extract of the inner bark of Uncaria tomentosa. A 1:1 strength means that the extract is made from equal amounts of plant material (Uncaria tomentosa bark) and extracting agent (in this case, grain alcohol and water). Most companies produce a weaker 1:2 extract which contains only 1 part plant material to 2 parts extracting material. Most of the alcohol in Royal Cat’s Claw Liquid Extract is removed from the product after extraction. Vegetable glycerin is substituted. Royal Cat’s Claw is gluten-free and vegan.Most Potent Species Royal Cat’s Claw is formulated from a species of Cat’s Claw known as Uncaria tomentosa, which grows in the Peruvian Amazon rainforest. Another species called Uncaria guianensis, also known as Uña de Gato, is a cheaper, more abundant species to collect and does not contain as many of the immune system-strengthening compounds as Uncaria tomentosa. Ultimately, the only ways to be sure you are getting the best Cat’s Claw is to identify the botanical name and know the manufacturer’s reputation.
Single-Source Indigenous. Many botanical companies buy their raw materials from middle-men suppliers in the United States. Instead of purchasing from middle-men, Whole World Botanicals does hands-on sourcing in Peru. We personally know the growers and collectors of the ingredients we use.
Ingredient companies are always looking for the cheapest sources, which means their raw materials change every time they buy, and the purchaser has no knowledge of where or who the raw materials come from. We know intimately the locations where our botanicals are grown and, in some cases, Whole World Botanicals has purchased land in order to wildcraft the botanicals that are not readily available. We have a relationship with our growers and collectors and have an ongoing social mission on their behalf.
Superior Processing and Testing. The plant material is collected in Peru and manufactured in the United States. Each batch undergoes Fingerprint analysis (IRTLC), to ensure purity. Processing the raw materials is also key to product potency. At Whole World Botanicals, we have complete control over collection, processing, manufacturing, and bottling. We are committed to the highest standards.
How does Cat’s Claw work?
Cat's Claw’s phytochemicals produce health benefits and include a group of oxidole alkaloids that support the immune system. Studies show that another group of chemicals called quinovic acid glycosides in Cat’s Claw have anti-inflammatory and antiviral actions. Cat’s Claw also has antioxidant chemicals (tannins, catechins and procyanidins) that are known to neutralize free radicals. In addition, it has plant sterols (beta-sitosterol, stigmasterol, and campesterol) that are beneficial in reducing inflammation. Several studies document the cell-repairing properties of Cat’s Claw and its cytotoxicity to mutated cells.*Can Royal Cat’s Claw be taken while undergoing chemotherapy or radiation treatment?
Royal Cat’s Claw (Uncaria tomentosa) has been shown in a scientific study to help prevent nausea in people undergoing chemotherapy treatment. Scientists also discovered that Cat’s Claw helps prevent loss of white blood cells caused by chemotherapy. In addition, it helps prevent immune system damage. Furthermore, Cat’s Claw does not interfere with cytotoxic effects of chemotherapy drugs.*Can Royal Cat’s Claw be taken long-term?
It is suggested that Royal Cat’s Claw be taken daily on an empty stomach for no longer than 3 months. For long-term usage (indefinitely), it can be safely taken 4-5 times a week.Is there any benefit to taking Royal Cat’s Claw liquid extract instead of the tea form?
There are no studies showing one is superior. Most people prefer the liquid extract form because it is so easy, but traditional usage is typically with the tea, and some naturopaths prefer the natural tea form. Effectiveness is also related to how much you take each day, and the strength of the tea. We cannot say one is better than the other; it’s really a question of personal choice.What is Cat’s Claw?

Help for lower digestive issues
“Royal Cat’s Claw Tea has been helpful with my lower digestive issues. I have leaky gut, food allergies and fibromyalgia. This tea has been very helpful; reducing symptoms and lessening food allergies. I also rarely get a cold when I take it.” ~Laura T.
Immune system support
“Royal Cat’s Claw Tea plays a huge role in reversing my symptoms from Hashimotos (leaky gut, constipation, low thyroid function, huge weight gain, etc.). I also had pain in my legs (could not squat without excruciating pain). I am using the tea to treat my leaky gut syndrome and the resulting immune system issues. It is working for me and is keeping my internal organs working better and my joint pain is almost gone. I trust your product.” ~Amelia R., OH
Good for the whole family
“I only trust Whole World Botanicals to produce unadulterated products. As much Cat’s Claw as we drink here, that’s important. Even my dog gets the tea in his gravy to reverse his arthritic leg pain and he is starting to walk normally again. Thank you for the work you are doing!” ~Amelia R.
Viana’s testimony for Cat’s Claw
“I had breast cancer more than 20 years ago. It was not early stage. And I had the most serious kind. I consulted three different oncologists. One said, “We will give you the strongest treatment we know. I thought to myself, ‘That’s going to kill me.’
I looked for something effective but not so dangerous. I was far from sure that I would survive. I chose another option which was very experimental at the time: I had a small dose of chemo every week for a year and a half. My hair got a bit thin, but it looked normal.
I had all the orthodox medical treatments that are known (except for bone marrow transplant), including chemotherapy for a year and a half. I had radiation treatments and a mastectomy. As soon as I was diagnosed, I changed my diet severely – cutting out all refined sugars including honey. I also cut out animal products and did organic vegetable and apple juicing.
After the mainstream treatments were finished, I started taking Royal Cat’s Claw and Royal Camu on a regular basis. I also took Royal Maca (I had an estrogen-negative cancer), plus Royal Chanca Piedra. I knew that it was important to keep my liver healthy (it detoxifies) and clean my colon (Cat’s Claw) to get toxins out, and keep at bay any inflammation. I knew that I had to kill the stray cancer cells by supporting the immune system so it could take care of those. I knew that Vitamin C is a tremendous immune system support. It fights inflammation to keep cells healthy. Also, I knew in addition to helping my liver, Royal Chanca Piedra helps with inflammation. I felt that in addition to healthy food, with my history of immune compromise and after the weakened state of my immune system after treatment, I needed these herbs to fully recover from my experience. I am healthy and have more than two decades of being in remission. I’m not a perfect eater and I do have a sweet tooth. Sometimes I get a sore tongue as a result of that. Then I take extra Royal Camu, which I take anyway on a daily basis. If I feel a little pain in my breast area (I’m sensitive and aware of any change in my body), I make a big pot of Royal Cat’s Claw Tea and drink at least 3 cups a day for several days.
When I have ice cream or something fatty, I always take some Royal Chanca Piedra to help me break down the fats and eliminate excess fat. I do that when I overeat, too. If my bowel movements are getting smaller or difficult to eliminate, I reach for Royal Cat’s Claw. Hormone receptors that affect mood are in the intestines, so when I feel low, I take more Royal Cat’s Claw. I’ll also take extra Royal Camu when I indulge my sweet tooth, because sugar is inflammatory— as are all white flour products. I take these steps to make up for my imperfections in diet.”

Growth of in vitro human breast cancer cells inhibited by Cat’s Claw
“Depletion of specific binding sites for estrogen receptor by Uncaria tomentosa.” Salazar, E. L., et al. Proc. West. Pharmacol. Soc. 1998; 41(1): 123–124. PMID:9836266 Italian researchers reported in a 2001 in vitro study that cat’s claw directly inhibited the growth of a human breast cancer cell line by 90%, while another research group reported that it inhibited the binding of estrogens in human breast cancer cells in vitro. Note: in vitro studies do not have nearly as much validity as in vivo studies.Warning: Do not self-treat when dealing with a potentially fatal disease. You must see your doctor. This is a test-tube study, not on a real person. Royal Cat’s Claw is not a medication to treat breast cancer.

Preparation and Dosing Considerations
Traditional PreparationTypically, the indigenous people of Peru boil 20-30 grams of Uncaria tomentosa inner bark in a liter of water for 30-60 minutes to prepare a tea. (If the tea is shredded, 30 minutes is sufficient.) This is then consumed throughout the day for several days to several months.
Infusion
Ten grams of dried Uncaria tomentosa inner bark can be boiled in one liter of water to produce a tea. Drinking 2-3 cups of this tea daily can be very beneficial for a person with immune system compromise for long-term use up to 3 months, 4 to 5 times a week only.
If you add lemon juice or vinegar to the decoction when simmering, you will extract more alkaloids and less tannins from the bark. Use about 1/2 teaspoon of lemon juice or vinegar per cup of water. Finely ground bark capsules are practically worthless.
Liquid Extract
Whole World Botanicals also offers Royal Cat’s Claw liquid extract. The usual therapeutic dosage of Uncaria tomentosa liquid extract is 1 to 4 ml per day. The liquid extract may be taken directly under the tongue or added to water or juice. It tastes good with chocolate!
Directions
Drink one-half cup of tea at least 15 minutes before eating or two hours after eating, 2-4 times daily or as directed by your healthcare practitioner. Do not take at bedtime if it interferes with your sleep. As with most herbs, it is advised to cycle on and off rather than to take it continuously. For example, 3 months on and one moth off or 4 days on and 3 days off (weekly).To prepare: Put 8 teaspoons of loose tea into 5 cups of boiling water. Reduce heat and simmer the tea in a pot without a lid for 30 minutes. Strain. Makes 4 cups of tea. It tastes best if taken hot or very cold. Ice cubes and stevia may be added. The tea may be stored in the refrigerator in a glass or plastic jar with a lid for up to one week.
For those with sensitive stomachs, add ½ teaspoon of lemon juice to each cup of water used in preparing the tea. This will bind up most of the tannic acid and make the tea less astringent.
Contraindications
Organ/Bone Marrow Transplant: Since Cat’s Claw activates and strengthens the immune system, its use is contraindicated before or following any organ or bone marrow transplant or skin graft.Anti-fertility: Cat’s Claw taken at a high dosage has been documented with anti-fertility properties and is contraindicated in persons seeking to get pregnant, but may not be considered as a reliable contraceptive.
Warning about Pharmaceutical Blood Thinners: Since Cat’s Claw contains chemical compounds which can reduce platelet aggregation and thin the blood, consult your physician if you are taking Coumadin® or other blood thinning drugs. Discontinue use one week to ten days prior to any major surgical procedure.
Warning about Low Blood Pressure: Since Cat’s Claw might lower your blood pressure, people with low blood pressure need to increase fluids and salt when taking Cat’s Claw more than once a day. Two alkaloids in Cat’s Claw have been documented to lower blood pressure. Individuals with low blood pressure or taking antihypertensive drugs should consult their physician and monitor their blood pressure levels while taking Cat’s Claw. Medications may need adjusting.
Keep away from children. Not to be used if you are pregnant or nursing.
Possible side effects
Stomach: Cat’s Claw requires sufficient stomach acid to help break down the tannins and alkaloids during digestion, and to aid in absorption. Avoid taking liquid extracts directly by mouth and dilute first in water or acidic juice. Smaller more frequent amounts may be taken by individuals with digestive issues.Tannic acid: If the tannic acid in Cat’s Claw is not well tolerated, try preparing Cat’s Claw tea with added lemon juice because it lowers the amount of tannic acid released from the Cat’s Claw bark.
Gastrointestinal Problems: Large dosages of Cat’s Claw (3–4 ml—approximately one teaspoon of liquid extract) may cause abdominal pain or gastrointestinal problems in some individuals. This is related to the tannin content. A small portion of people may experience diarrhea or loose stools, but this tends to be mild and dissipate with continued use. Discontinue use or reduce dosage if diarrhea persists longer than 3–4 days.
Drug Interactions
Due to its immunostimulant effects and the possible interference of Cat’s Claw it should not be used with medications intended to suppress the immune system, such as cyclosporine or other medications prescribed following an organ transplant.Preparation and Dosing Considerations

Cat’s Claw (Uña de Gato in Spanish) is the bark and root parts of a woody vine which grows in the Peruvian Amazon. Whole World Botanicals uses Uncaria tomentosa in its Royal Cat’s Claw because it is the most potent species of this plant and offers unique benefits listed below.Through scientific research, Cat’s Claw has been shown to
- Strengthen the immune system*
- Promote healthy inflammation response in auto-immune conditions, including lupus, asthma, arthritis, Crohn’s Disease, etc.*
- Promote a healthy CRP (C-reactive protein) in the blood – associated with plaque buildup in arteries*
- Increase cell death (apoptosis) of abnormal cells*
- Repair DNA of mutated cells*

What makes Royal Cat’s Claw royal?
Superior Potency Royal Cat’s Claw is a very potent 1:1 liquid extract of the inner bark of Uncaria tomentosa. A 1:1 strength means that the extract is made from equal amounts of plant material (Uncaria tomentosa bark) and extracting agent (in this case, grain alcohol and water). Most companies produce a weaker 1:2 extract which contains only 1 part plant material to 2 parts extracting material. Most of the alcohol in Royal Cat’s Claw Liquid Extract is removed from the product after extraction. Vegetable glycerin is substituted. Royal Cat’s Claw is gluten-free and vegan.Most Potent Species Royal Cat’s Claw is formulated from a species of Cat’s Claw known as Uncaria tomentosa, which grows in the Peruvian Amazon rainforest. Another species called Uncaria guianensis, also known as Uña de Gato, is a cheaper, more abundant species to collect and does not contain as many of the immune system-strengthening compounds as Uncaria tomentosa. Ultimately, the only ways to be sure you are getting the best Cat’s Claw is to identify the botanical name and know the manufacturer’s reputation.
Single-Source Indigenous. Many botanical companies buy their raw materials from middle-men suppliers in the United States. Instead of purchasing from middle-men, Whole World Botanicals does hands-on sourcing in Peru. We personally know the growers and collectors of the ingredients we use.
Ingredient companies are always looking for the cheapest sources, which means their raw materials change every time they buy, and the purchaser has no knowledge of where or who the raw materials come from. We know intimately the locations where our botanicals are grown and, in some cases, Whole World Botanicals has purchased land in order to wildcraft the botanicals that are not readily available. We have a relationship with our growers and collectors and have an ongoing social mission on their behalf.
Superior Processing and Testing. The plant material is collected in Peru and manufactured in the United States. Each batch undergoes Fingerprint analysis (IRTLC), to ensure purity. Processing the raw materials is also key to product potency. At Whole World Botanicals, we have complete control over collection, processing, manufacturing, and bottling. We are committed to the highest standards.
How does Cat’s Claw work?
Cat's Claw’s phytochemicals produce health benefits and include a group of oxidole alkaloids that support the immune system. Studies show that another group of chemicals called quinovic acid glycosides in Cat’s Claw have anti-inflammatory and antiviral actions. Cat’s Claw also has antioxidant chemicals (tannins, catechins and procyanidins) that are known to neutralize free radicals. In addition, it has plant sterols (beta-sitosterol, stigmasterol, and campesterol) that are beneficial in reducing inflammation. Several studies document the cell-repairing properties of Cat’s Claw and its cytotoxicity to mutated cells.*Can Royal Cat’s Claw be taken while undergoing chemotherapy or radiation treatment?
Royal Cat’s Claw (Uncaria tomentosa) has been shown in a scientific study to help prevent nausea in people undergoing chemotherapy treatment. Scientists also discovered that Cat’s Claw helps prevent loss of white blood cells caused by chemotherapy. In addition, it helps prevent immune system damage. Furthermore, Cat’s Claw does not interfere with cytotoxic effects of chemotherapy drugs.*Can Royal Cat’s Claw be taken long-term?
It is suggested that Royal Cat’s Claw be taken daily on an empty stomach for no longer than 3 months. For long-term usage (indefinitely), it can be safely taken 4-5 times a week.Is there any benefit to taking Royal Cat’s Claw liquid extract instead of the tea form?
There are no studies showing one is superior. Most people prefer the liquid extract form because it is so easy, but traditional usage is typically with the tea, and some naturopaths prefer the natural tea form. Effectiveness is also related to how much you take each day, and the strength of the tea. We cannot say one is better than the other; it’s really a question of personal choice.What is Cat’s Claw?

Cat’s Claw also has antioxidant chemicals (tannins, catechins and procyanidins) that are known to neutralize free radicals. In addition, it has plant sterols (beta-sitosterol, stigmasterol, and campesterol) that are beneficial in reducing inflammation. Several studies document the cell-repairing properties of Cat’s Claw and its cytotoxicity to mutated cells.*Can Royal Cat’s Claw be taken while undergoing chemotherapy or radiation treatment?
Royal Cat’s Claw (Uncaria tomentosa) has been shown in a scientific study to help prevent nausea in people undergoing chemotherapy treatment. Scientists also discovered that Cat’s Claw helps prevent loss of white blood cells caused by chemotherapy. In addition, it helps prevent immune system damage. Furthermore, Cat’s Claw does not interfere with cytotoxic effects of chemotherapy drugs.*Can Royal Cat’s Claw be taken long-term?
It is suggested that Royal Cat’s Claw be taken daily on an empty stomach for no longer than 3 months. For long-term usage (indefinitely), it can be safely taken 4-5 times a week.Is there any benefit to taking Royal Cat’s Claw liquid extract instead of the tea form?
There are no studies showing one is superior. Most people prefer the liquid extract form because it is so easy, but traditional usage is typically with the tea, and some naturopaths prefer the natural tea form. Effectiveness is also related to how much you take each day, and the strength of the tea. We cannot say one is better than the other; it’s really a question of personal choice.DISCLAIMER: Whole World Botanicals does not recommend self-treatment with any of our products.

Help for lower digestive issues
“Royal Cat’s Claw Tea has been helpful with my lower digestive issues. I have leaky gut, food allergies and fibromyalgia. This tea has been very helpful; reducing symptoms and lessening food allergies. I also rarely get a cold when I take it.” ~Laura T.
Immune system support
“Royal Cat’s Claw Tea plays a huge role in reversing my symptoms from Hashimotos (leaky gut, constipation, low thyroid function, huge weight gain, etc.). I also had pain in my legs (could not squat without excruciating pain). I am using the tea to treat my leaky gut syndrome and the resulting immune system issues. It is working for me and is keeping my internal organs working better and my joint pain is almost gone. I trust your product.” ~Amelia R., OH
Good for the whole family
“I only trust Whole World Botanicals to produce unadulterated products. As much Cat’s Claw as we drink here, that’s important. Even my dog gets the tea in his gravy to reverse his arthritic leg pain and he is starting to walk normally again. Thank you for the work you are doing!” ~Amelia R.
Viana’s testimony for Cat’s Claw
“I had breast cancer more than 20 years ago. It was not early stage. And I had the most serious kind. I consulted three different oncologists. One said, “We will give you the strongest treatment we know. I thought to myself, ‘That’s going to kill me.’
I looked for something effective but not so dangerous. I was far from sure that I would survive. I chose another option which was very experimental at the time: I had a small dose of chemo every week for a year and a half. My hair got a bit thin, but it looked normal.
I had all the orthodox medical treatments that are known (except for bone marrow transplant), including chemotherapy for a year and a half. I had radiation treatments and a mastectomy. As soon as I was diagnosed, I changed my diet severely – cutting out all refined sugars including honey. I also cut out animal products and did organic vegetable and apple juicing.
After the mainstream treatments were finished, I started taking Royal Cat’s Claw and Royal Camu on a regular basis. I also took Royal Maca (I had an estrogen-negative cancer), plus Royal Chanca Piedra. I knew that it was important to keep my liver healthy (it detoxifies) and clean my colon (Cat’s Claw) to get toxins out, and keep at bay any inflammation. I knew that I had to kill the stray cancer cells by supporting the immune system so it could take care of those. I knew that Vitamin C is a tremendous immune system support. It fights inflammation to keep cells healthy. Also, I knew in addition to helping my liver, Royal Chanca Piedra helps with inflammation. I felt that in addition to healthy food, with my history of immune compromise and after the weakened state of my immune system after treatment, I needed these herbs to fully recover from my experience. I am healthy and have more than two decades of being in remission. I’m not a perfect eater and I do have a sweet tooth. Sometimes I get a sore tongue as a result of that. Then I take extra Royal Camu, which I take anyway on a daily basis. If I feel a little pain in my breast area (I’m sensitive and aware of any change in my body), I make a big pot of Royal Cat’s Claw Tea and drink at least 3 cups a day for several days.
When I have ice cream or something fatty, I always take some Royal Chanca Piedra to help me break down the fats and eliminate excess fat. I do that when I overeat, too. If my bowel movements are getting smaller or difficult to eliminate, I reach for Royal Cat’s Claw. Hormone receptors that affect mood are in the intestines, so when I feel low, I take more Royal Cat’s Claw. I’ll also take extra Royal Camu when I indulge my sweet tooth, because sugar is inflammatory— as are all white flour products. I take these steps to make up for my imperfections in diet.”

Growth of in vitro human breast cancer cells inhibited by Cat’s Claw
“Depletion of specific binding sites for estrogen receptor by Uncaria tomentosa.” Salazar, E. L., et al. Proc. West. Pharmacol. Soc. 1998; 41(1): 123–124. PMID:9836266 Italian researchers reported in a 2001 in vitro study that cat’s claw directly inhibited the growth of a human breast cancer cell line by 90%, while another research group reported that it inhibited the binding of estrogens in human breast cancer cells in vitro. Note: in vitro studies do not have nearly as much validity as in vivo studies.Warning: Do not self-treat when dealing with a potentially fatal disease. You must see your doctor. This is a test-tube study, not on a real person. Royal Cat’s Claw is not a medication to treat breast cancer.

PMID: 1317985 The conclusion of this study was that a prevelent element in Cat’s Claw is an anti-inflammatory agent beneficial in maintaining heart health and reducing stickiness of blood and helping prevent blood clots.Cat’s Claw increased cell death of human bladder cancer cells (in vitro)
“Quinovic acid glycosides purified fraction from Uncaria tomentosa induces cell death by apoptosis in the T24 human bladder cancer cell line.” Dietrich F, Kaiser S, Rockenbach L, Figueiró F, Bergamin LS, da Cunha FM, Morrone FB, Ortega GG, Battastini AM. Food Chem Toxicol. 2014 May;67:222-9. PMID: 24607820 In this study, scientists found that Cat’s Claw decreased the growth and viability of cancer in both cell lines and it induced cancer cell apoptosis (death). Their conclusion was that Cat’s Claw is powerful in its ability to inhibit the growth of human bladder cancer cells and they suggested it “may become a potential therapeutic agent for the prevention and/or treatment of this cancer.”Cat’s Claw enhances DNA repair in human skin cultures – may be good for use in sunscreen products
“A water soluble extract from Uncaria tomentosa (Cat's Claw) is a potent enhancer of DNA repair in primary organ cultures of human skin.” Mammone T, Akesson C, Gan D, Giampapa V, Pero RW. Phytother Res. 2006 Mar;20(3):178-83 PMID: 16521105 In this study, scientists created human skin cultures and irradiated them with UVB rays to determine Cat's Claw has ability to enhance DNA repair in human skin. They found that Cat’s Claw reduced skin cell death and this protection was accounted for by an increase in DNA repair. Based on these results, it was concluded that Cat’s Claw was a natural plant extract worthy of further consideration as a sunscreen product. “Cat's Claw is the only documented natural source of components that can simultaneously regulate both DNA repair and anti-inflammation.”Cat’s Claw helps prevent side-effects of mainstream cancer therapies of chemotherapy and radiation
