Cat's claw is a woody vine native to the Amazon rainforest and other tropical areas of Central and South America. It has a hook-like thorn that grows along the vine and resembles a cat's claw. For over 2000 years, indigenous tribes have used the bark and root of this plant in traditional medicine to treat a variety of ailments.
Today, it's a popular herbal supplement in the United States and Europe, often marketed for its potential to support the immune system and reduce inflammation. But what exactly does the science say?
In this article, we will find out what cat's claw is, its traditional uses, potential benefits, and side effects to help you make an informed decision.
What Is Cat's Claw Used For?
Cat's Claw has a long history of use in traditional medicines, which has made its way into a wide range of modern applications.
Inflammatory Conditions:
Dealing with inflammatory issues is one of the most common uses of cat's claw. In conditions like osteoarthritis and rheumatoid arthritis, it helps relieve pain and improve function. It has anti-inflammatory properties that come from its ability to inhibit the production of certain pro-inflammatory compounds in the body, such as the cytokine tumor necrosis factor (TNF)-alpha and the transcription factor nuclear factor kappa-B (NF-κB).
Immune System Support:
Cat's claw is frequently used to boost the immune system. Some studies show that certain compounds, particularly pentacyclic oxindole alkaloids, can stimulate the activity of white blood cells (phagocytes), which are a crucial part of the body's defense against infection. It has been traditionally used to help fight viral infections and was even promoted for use in HIV/AIDS patients.
Digestive Health:
In its native region, a decoction of cat's claw bark has been used to treat digestive issues, gastric ulcers, intestinal disorders, and other digestive complaints. It is also used by some for conditions like diverticulitis, colitis, and "leaky gut syndrome."
Other Traditional Uses:
This plant has a long history of use for many other health issues, including arthritis, weakness, skin disorders (abscesses, acne), allergies, asthma, cancer, fevers, hemorrhage, rheumatism, and wounds, as well as for disease prevention and recovery from childbirth
Cat's Claw Benefits:
Research has shown several areas where cat's claw shows potential promise. The most widely studied and supported benefits are related to its anti-inflammatory and immune-boosting effects.
Anti-inflammatory Effects
Cat's Claw has the most compelling scientific evidence to reduce inflammation. Multiple research studies and trials have shown that cat's claw extract significantly reduces pain during activity in people with knee osteoarthritis and rheumatoid arthritis.
Immunomodulatory Activity
Cat's claw is believed to have a balancing effect on the immune system. It can both stimulate an underactive immune response and calm an overactive one. The pentacyclic oxindole alkaloids (POAs) in cat's claw are often cited as the key compounds responsible for this immune-stimulating effect.
Cat's Claw Dosage
There is no standardized dose for cat's claw. Dosage recommendations vary depending on the form of supplement and its concentration. Some general guidelines are:
Common Forms: Cat's claw is available as capsules, tablets, liquid extracts, tinctures, and tea (decoction).
General Dosage: A typical traditional dose is 1 gram of root bark taken 2 to 3 times daily. When taking a root bark extract, a 250 to 300 mg daily dose has been recommended. Another source suggests a daily dose of 20-350 mg of dried stem bark for extracts or 300-500 mg in capsule form, divided into 2-3 separate doses throughout the day.
Always start with the low dose. Consult your healthcare provider for personalized dosage advice. Also, follow the vendor’s instructions.
Side Effects of Cat's Claw
Cat's claw is generally well tolerated when taken by mouth for short periods up to 6 months. Some side effects have been reported:
Common Side Effects
Nausea, diarrhea, stomach discomfort, vomiting, dizziness, and headaches are the most common side effects of cat's claw.
