Cat’s Claw is a tropical vine that grows in rainforest and jungle areas in South America and Asia. Some cultures refer to the plant as the “Sacred Herb of the Rain Forest”. This vine gets its name from the small thorns at the base of the leaves, which looks like a cat’s claw. These claws enable the vine to attach itself around trees climbing to a heights up to 100 feet.

The plant is considered a valuable medicinal resource and is protected in Peru. Although scientific research has just recently begun to explore cat’s claw, many cultures native to the South American rain forest areas have used this herb for hundreds of years.

Current studies show it may have positive effects on, and can boost the body’s immune system. With recent fear of HIV, studies on cat’s claw have started to move quickly.

Why they started to move that fast? Because the recent studies about this herb extract shows that its effects are huge. The change of a patient who is taking cat’s claw could be notorious.

According to the National Cancer Institute (NCI), there are 3000 plant extracts that can kill cancer cells, 70 percent of these plants being found only in the rain forest. The fertile environment provided by the rain forest, due to the constant rain from January to December and the 75-80 degree Fahrenheit temperatures, allows the plants grown to be amazingly rich in alkaloids and other medicinal compounds. When the Ashaninka harvest the plant, they work intelligently to keep it perpetually healthy.

Individual plants are never completely harvested. Only one third of their roots are collected at any time and then no more root is harvested from that plant for the next ten years, allowing re-growth in the remaining root. Because the Ashaninka are a generous people, they see no benefit in hoarding the cat’s claw for themselves. As their homelands continue to be destroyed by deforestation, they want to make sure that the plant’s healing properties continue on.

Some cat’s claw roots have good spirits, POAs, while others tetracyclic oxindole alkaloids, TOAs, which do not help the immune system at all. Since Uncaria tomentosa plants look almost identical, it is hard to tell if they contain healing properties or non-helpful properties. Plants containing POAs one year may contain TOAs the following year because their alkaloid chemotypes change at will. After scientists discovered that they could “see” the presence of TOAs using the HPLC technology, they gained the ability to harvest cat’s claw root extracts with POAs consistently. Because buying products that contain TOAs will only benefit the cat’s claw distributor due to its canceling effects on POAs, it is important to read the label of the cat’s claw root product you are considering buying.

The inner bark of the plant is the source of cat’s claw’s active alkaloid compounds, but the bark itself is indigestible and poorly absorbed, if at all, by the human digestive system. Fortunately, however, cat’s claw is now readily available in the form of easily absorbed teas, tinctures and capsules, but it’s probably best to start with low doses to ensure freedom from any possible side effects. And as recommended therapeutic doses vary between 750 and 3,000 mg per day, it’s always worth talking things over with your physician or a reputable herbal practitioner before beginning any program of supplementation. But the potential benefits of cat’s claw appear so promising that this is not a herb you should ignore.
