Why Choose Royal Cat’s Claw?

Superior Potency

The liquid extract of Royal Cat’s Claw is very strong (1:1 potency). Most companies have a 1:2 (only half the strength) or even 1:4 potency.

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 all of the immune system strengthening compounds of Uncaria tomentosa. Ultimately, the only ways to be sure you are getting the best Cat’s Claw is to know the manufacturer’s reputation and identify the botanical name.

Superior Processing and Testing

The plant material is collected in Peru and manufactured in the United States. Heavy metal content is undetectable in the Royal Cat’s Claw liquid extract. Each batch undergoes Fingerprint analysis (IRTLC) and Gas Chromatography (potency testing). How the raw materials are processed is also key to product potency. At Whole World Botanicals, we have complete control over collection, processing, and manufacturing, and bottling. We are committed to the highest standards.

Single-Source Indigenous

Instead of purchasing raw materials from middle-men, Whole World Botanicals does hands-on sourcing in Peru. 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. Not so with Whole World Botanicals – we actually know the names of our growers and collectors. We know intimately the locations where our botanicals grow and, in some cases, own the land. We do what we can to support the indigenous people and attend to their financial, educational, and health needs.

Botanical in the Peruvian Amazon

This Cat’s Claw (Uncaria tomentosa) vine has been peeled with the help of a machete. The part lifted from the vine is the bark – the principal part that is used. The outer layer of the bark is scraped to remove tiny insects, fungal growth, etc.

Cat’s Claw vine (Uncaria tomentosa) has characteristic ‘claws’ which gives the plant its name. It’s is commonly known as Uña de Gato in South America.

As we commemorate Indigenous Peoples' Day – which this year falls on Monday, October 14th – we would like to recognize the vital role of Indigenous communities in preserving the Amazon rainforest, especially in the face of unprecedented climate challenges. The Amazon rainforest is home to over 350 Indigenous groups. These communities have stewarded the Amazon rainforest for millennia, and play a vital role in preserving the health of the rainforest. It’s a symbiotic relationship, as the rainforest affects most aspects of their daily life, livelihood, and culture.

Dear Customers of Whole World Botanicals,

You are our partners in helping to transform the world through the use of herbal medicine and via our work to protect its habitat. For that reason, Elena and I want to share with you some recent disturbing phone reports we’ve had from Peru.

Taking Maca Wrong
Taking Maca Wrong
I regularly receive emails and voicemails with questions about Maca. Some say, “I’ve tried Maca before, but it doesn’t work for me. Why should I try your Royal Maca?” Or, “I bought your Royal Maca, and I’ve been taking it, but my symptoms haven’t changed.” Or, “I’ve been taking two capsules a day for a year, and it’s cut my number of hot flashes in half, but I still get too many! I think I’m taking it all wrong!” Occasionally, a customer even complains that their symptoms got worse after taking Royal Maca!
