Additional Information About Uncaria tomentosa (Cat’s Claw)

Uncaria tomentosa, also known as uña de gato or Samento, hails from the Uncaria varieties native to China, Peru, and Africa. Steeped in Traditional Chinese Medicine for over a millennium, its surge in popularity in the West came notably through Nutramedix's "Samento" product.

Traditional Use
The inner bark of Uncaria tomentosa, a woody vine with hooked claw-shaped horns, has been integral to South American native remedies for asthma, urinary tract inflammation, arthritis, rheumatism, bone pains, fevers, and Diabetes. 

Growing Conditions
Thriving in the rainforests of Central and South America, Uncaria tomentosa's woody vines, reaching up to 100 feet, are characterized by yellow trumpet flowers. Both root and vine bark are utilized in herbal applications within the Rubiaceae family.

Crucially, distinguish Uncaria tomentosa (common Cat’s Claw) from Uncaria rhynchophylla (Chinese Cat’s Claw or Gou Teng), historically employed for different manifestations of Borrelia. The former is associated with arthritic-type Borrelia, while the latter is linked to neuroborreliosis, neurological disorders and seizures.

Uncaria tomentosa boasts a diverse array of constituents, including alkaloids, glycosides, flavonoids, and sterols, with variations dictated by geographical regions.

Scientific Studies
The plant's benefits emerge prominently in chronic infections, with a minimum of 60 days of continuous use recommended to notice results. Despite minimal antibacterial action, Uncaria tomentosa stimulates the immune system, with potential benefits against viruses and Candida organisms noted in some in vitro studies. It actively reduces inflammatory mediators such as prostaglandin E2, nitric oxide, COX-2, and NFkappaB.

Cat's Claw Side Effects
While a highly useful botanical, caution is recommended. Uncaria tomentosa is contraindicated during pregnancy and in cases of autoimmune conditions, organ transplants, or immunosuppressive drug use. Cat’s Claw requires special consideration with blood thinners and prior to surgery. Caution is advised for individuals with kidney damage or low blood pressure, with potential side effects encompassing nausea, diarrhea, and dizziness.

    Great quality tincture! It tastes about as good as cats claw can, and isn’t overly bitter. It works very well for me as an anti-inflammatory. Effects are fast, and the potency is strong enough (1:4) to be effective, but not so strong that a dose is one drop. The bottle has a note saying an dose can be up to 15 drops, which leaves a lot of room to find the right dose.

    I switched from taking Nutramedix ‘samento’ and I find this works just as good if not better for a fraction of the price. Thank you!!!!

Free Lyme Protocol Guide - Apex Botanicals


FREE Herbal Protocol Guide for Lyme &

This guide, written by our Lyme-literate experts, is designed to offer clarity amidst the confusion of endless treatment choices.

You'll gain insights into the nuanced physiological effects of the Lyme bacteria on various body systems and how herbs and supplements play a pivotal role in addressing these challenges.

By the end you'll have created your very own customized treatment protocol, tailored to your unique needs!


What makes Apex Botanical tinctures different from other herbal tinctures?

Our tinctures stand out due to the premium quality of herbs we use. Crafted at a concentration of 1:4, our herbal tinctures prioritize both potency and effectiveness.

Unlike many other companies that employ a uniform alcohol percentage across all products, our approach is nuanced. We tailor the alcohol concentration for each herb based on the distinct medicinal properties of the plant.

This strategy reflects our commitment to a sophisticated extraction of medicinal compounds, effectively setting Apex Botanicals apart in the realm of herbal tinctures.

How should I consume my herbal tincture?

Herbal tinctures are generally taken on an empty stomach (1 hour before and after meals). They can be taken directly or added to 1oz of water if the taste is hard to swallow.

Dosing of herbal tinctures will generally vary from 1 drop once per day up to 1 tsp 3 times per day. When taking anti-microbial herbal tinctures, starting at a lower dose and increasing slowly is the general rule of thumb.

*Be sure to speak with your primary care provider to determine the correct dose for your needs.

How long should I take my herbal tincture for?

The length of time a tincture should be taken will vary considerably based on your state of health, the infection / symptom you’re trying to treat and other medications or treatments you are concurrently taking.

Most people with chronic tick-borne infections take an herbal tincture for between 3 months and 2 years.

As a general rule, its recommended to take an herbal tincture for at least 1 month to see the best results.

Are herbal tinctures safe for children?

Generally speaking, it is safe for children to consume herbal tinctures, but dosing should be adjusted. Refrence 'Clarks Rule' for further information.

*Always consult your primary care provider before starting a new protocol or giving your child herbal tinctures.

Are herbal tinctures safe during pregnancy or while breastfeeding?

Some herbs are strictly contraindicated in pregnancy and should be avoided. We do our best to indicate this on the product information page but are not held liable for any errors or omissions.

If you are pregnant or breastfeeding consult your primary care provider before consuming any herbal tinctures.

Will my herbal tincture interact with medications or supplements?

Interactions of herbal tinctures with medications or supplements do exist. We strongly recommended consulting with your primary care provider or pharmacist before taking any herbal tinctures if you are concerned about potential contraindications.

What does a 1:4 ratio imply and how does it compare to 1:2 or 1:5+?

The ratio describes the concentration of a tincture. We use a 1:4 ratio, meaning 1 part dried herb (in grams) to 4 parts menstruum (the combined alcohol and herb).

A ratio of 1:5 has more liquid to the same amount of herb and is therefore more diluted.

A ratio of 1:10 or higher is very diluted and requires very high daily doses and is not recommended.

Tinctures made at 1:2 are often too concentrated for Lyme patients and commonly induce Herx reactions that can be very intense.

Most tinctures on the market are made at 1:5. We’ve chosen to use 1:4 to ensure greater potency while still being very safe and tolerable.

Does higher alcohol content mean an herbal tincture is more or less potent?

Using the correct alcohol percentage to extract the specific medicinal constituents of that herb is of highest importance when making a tincture. Using more or less alcohol essentially reflects the chemical nature of the compounds that we want to extract into the liquid portion.

A tincture made at 40% versus one made at 80% is not twice at strong. It simply implies that for the first herb, 40% alcohol will optimally extract the medicinal qualities. For the second herb, 80% is the concentration for optimal extraction.

We’ve gone to great lengths to ensure that our tinctures are made using the correct concentrations.

*Please note that not all herbal tinctures on the market are made with the appropriate alcohol concentration so use our site as a reference or conduct your own research to make sure you’re purchasing the best formulated tincture possible.
