Dosing

Adults (18 years and older):

There is no proven effective dose for cat's claw. Capsules, extracts, tinctures, decoctions, and teas are commercially available. As a capsule, 20 milligrams to 25 grams have been used, often taken in divided does.

Cat's claw is also available in preparations for the skin, but no specific doses have been shown to be safe or effective.

Children (younger than 18 years):

The dosing and safety of cat's claw have not been studied thoroughly in children, and it is recommended that doses are discussed with the child's healthcare provider before starting therapy.

Safety

DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.

Allergies

People with allergies to plants in the Rubiaceae family or any species of Uncaria may be more likely to have allergic reactions to cat's claw. A typical allergic reaction may be itching or severe rash. Allergic inflammation of the kidneys has been reported.

Side Effects and Warnings

Few side effects have been reported from using cat's claw at recommended doses. Most side effects are believed to be rare, and some side effects are theoretical and have not been reported in humans. Examples of possible side effects include stomach discomfort, nausea, diarrhea, slow heartbeats or altered rhythm of heartbeats, kidney disease, acute kidney failure, neuropathy, decreases in estrogen or progesterone levels, and an increased risk of bleeding. Because cat's claw theoretically may increase the risk of bleeding, patients may need to stop taking cat's claw before some surgeries and this needs to be discussed with a qualified healthcare provider. Caution is advised in patients with bleeding disorders or taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary.

Some natural medicine experts discourage the use of cat's claw in people with conditions affecting the immune system, such as AIDS or HIV, some types of cancer, multiple sclerosis, tuberculosis, and rheumatologic diseases (rheumatoid arthritis, lupus, etc.). However, there are no specific studies or reports in this area, and the risks of cat's claw use in people with these conditions are not clear.

Many tinctures contain high levels of alcohol and should be avoided when driving or operating heavy machinery.

Pregnancy and Breastfeeding

Cat's claw cannot be recommended during pregnancy or breastfeeding. Historically, cat's claw has been used to prevent pregnancy and to induce abortion. Women who are pregnant or wish to become pregnant should not take cat's claw. Many tinctures contain high levels of alcohol, and should be avoided during pregnancy.
