Cat's Claw (Uncaria tomentosa): What We Published in August 2023

In August 2023 we focused on Cat's Claw — a plant-based supplement from the Amazon that many people use for immune and joint support. If you saw the original post, you know we covered what Cat's Claw is, why people take it, what the research says, and practical tips for using it safely. Below is a clear, useful summary so you can decide if it fits your routine.

What Cat's Claw Is and Why People Use It

Cat's Claw (scientific name Uncaria tomentosa) is a vine with hooked thorns that looks like a cat’s claw — that's where the name comes from. People take it as a capsule, extract, or tea for two main reasons: to support the immune system and to ease joint pain or inflammation. The plant contains compounds that may affect immune signaling and inflammation, which is why it’s popular among those with mild arthritis or who want general immune support.

We explained that it’s not a miracle cure. Instead, think of Cat's Claw as a herbal option with some promising but limited human data. Several small clinical trials and lab studies show modest benefits for joint pain and immune markers, but larger high-quality trials are still needed.

How to Use It, Dosage, and Safety Tips

Most supplements use either a powdered extract or a concentrated liquid. Typical doses in studies vary, often falling between 250 mg and 3,000 mg per day depending on the extract strength. For beginners, a common approach is to follow the product label or start at a low dose to see how your body reacts.

Watch for side effects: mild stomach upset, dizziness, and headache are the most reported. People on immune-suppressing drugs, pregnant or breastfeeding women, and those with autoimmune conditions should avoid Cat's Claw unless a doctor clears it. Also, it can interact with blood thinners and certain blood pressure medicines, so check with your healthcare provider first.

When choosing a product, look for clear labeling (standardized extract percent or exact mg), third-party testing, and a reputable brand. Prefer extracts that list active compounds or give a standardized alkaloid or polyphenol range. If you choose tea, know that potency varies a lot compared to extracts or capsules.

To wrap up what we published in August: Cat's Claw is a well-known herbal option for inflammation and immune support with some supportive, but limited, human data. Use caution if you’re on medication or have a specific health condition, and buy from brands that test their products.
