Cat’s Claw (Uncaria tomentosa) is a tropical vine native to the Amazon rainforest and other areas of Central and South America. Recognizable by its claw-shaped thorns, this plant has garnered widespread attention for its potential medicinal properties, rooted in centuries of use by Indigenous cultures and supported by emerging scientific studies.
Cultural and Historical Background
Indigenous tribes in the Amazon have utilized Cat’s Claw for hundreds, if not thousands, of years. Known locally as “uña de gato,” it has been revered as a remedy for a variety of ailments. Traditional uses include treating inflammation, infections, digestive issues, and wounds. Shamans also used Cat’s Claw in spiritual ceremonies, believing it had protective and purifying properties.
The plant’s significance extends to the Asháninka people of Peru, one of the largest Indigenous groups in the Amazon. For them, Cat’s Claw is considered a sacred plant, integral to maintaining physical and spiritual health.
Potential Medical Uses
Modern interest in Cat’s Claw began in the late 20th century, leading to its inclusion in herbal supplements and natural health remedies. It is often marketed for its purported abilities to:

- Reduce inflammation – Its anti-inflammatory properties are said to alleviate conditions like arthritis and inflammatory bowel disease (IBD).
- Support digestive health – Traditionally used to treat ulcers and other gastrointestinal problems, Cat’s Claw may help soothe the gut.
- Act as an antioxidant – Compounds in Cat’s Claw may neutralize harmful free radicals, promoting overall cellular health.
- Combat viral infections – Some studies suggest that it may have antiviral properties, potentially aiding in the treatment of certain viral infections.
Active Compounds
The plant’s potential benefits are attributed to its rich phytochemistry, which includes alkaloids, flavonoids, and tannins. The most studied compounds are oxindole alkaloids, which are believed to influence immune response and have anti-inflammatory effects.
Scientific Studies
While traditional uses of Cat’s Claw are well-documented, scientific research is still evolving. Here are some notable findings:
- Arthritis: A 2001 study published in The Journal of Rheumatology found that Cat’s Claw extract reduced joint pain and swelling in patients with rheumatoid arthritis.
- Digestive health: A 2011 study suggested that Cat’s Claw could help manage symptoms of Crohn’s disease and IBD, though more research is needed.
- Immune system: Research has indicated that Cat’s Claw may enhance white blood cell activity, potentially supporting the immune system against infections.
- Antiviral properties: Laboratory studies have demonstrated its inhibitory effects on certain viruses, including herpes simplex. However, clinical trials in humans are sparse.
Side Effects and Precautions
Despite its potential, Cat’s Claw is not without risks. Reported side effects include:

Additionally, it may interact with medications, including blood thinners, immune suppressants, and anti-hypertensive drugs. Pregnant or breastfeeding women and those with autoimmune disorders should avoid using Cat’s Claw due to potential complications.
Conclusion
Cat’s Claw represents a fascinating intersection of ancient wisdom and modern science. While its potential as a natural remedy is promising, further clinical research is essential to validate its efficacy and safety for widespread use. For those considering Cat’s Claw as a supplement, consulting with a healthcare provider is crucial to ensure its safe and effective use.
