Swanson Cat’s Claw is a dietary supplement containing an extract of cat’s claw. In the literature, the plant is also known as vilcacora.

The preparation helps to enhance immunity and strengthen the organism’s health. Because of its powerful anti-inflammatory and analgesic properties, it is often used in the treatment of rheumatic diseases and musculoskeletal system problems. It can also support the therapy of more serious conditions, such as cancer.

Cat’s claw, or vilcacora (Uncaria tomentosa) is a vine found in tropical Amazon rainforests. Its bark is a valued medicinal material – it contains more than 50 different biologically active substances that have a positive effect on the human organism. Those considered to be the most active are oxindole alkaloids (such as mitraphylline, rhynchophylline, isopteropodine, uncarines C, D and E, and hirsuteine); other substances of great importance are triterpenes, procyanidins, plant steroids (such as highly anti-inflammatory β-sitosterol), and quinic acid glycosides (powerful antiviral properties).

Support for the immune system
Cat’s claw is a powerful modulator of the immune system. It affects a multitude of immune system elements that determine the cell-mediated and non-specific immunity of the organism.

Oxindole alkaloids present in the plant’s bark increase the level of the crucial cells of the immune system (mainly B and T lymphocytes) and stimulate the activity of granulocytes. Moreover, they increase the efficiency phagocytosis, thanks to which pathogenic microorganisms and improperly structured cells are devoured by specialised phagocytes. They also stimulate macrophages to produce two cytokines, IL-1 and IL-2, which are two of the key components of the immune system.

Inflammation reduction
Scientific research has demonstrated that cat’s claw extracts reduce inflammation as efficiently as popular pharmaceuticals of the NSAID group (like ibuprofen, naproxen). However, their superiority lies in the fact that they cause no side effects, such as stomach irritation or cartilage damage.

The main mechanism responsible for the anti-inflammatory properties of cat’s claw is its great ability to inhibit the production of the pro-inflammatory cytokine TNF-α and the synthesis of NF-kB. Its another ability of relevance is that to reduce the release of eicosanoids, including the most active one, prostaglandin E2 (PGE2).

Because of its powerful anti-inflammatory and analgesic properties, the cat’s claw bark extract are often used to alleviate problems with the musculoskeletal system. The plant can support the treatment of arthritis, rheumatoid arthritis, and bone and joint inflammations. Tests on people with highly developed degenerative lesions within their knees demonstrated that even 4 weeks of cat’s claw bark extract supplementation are enough to alleviate pain, increase joint mobility, and reduce morning stiffness. Importantly, throughout the supplementation period, no negative changes were observed in terms of haematology and liver function tests.

Combat against free radicals and oxidative stress
Cat’s claw bark contains a multitude of compounds with antioxidant properties. Alkaloids, proanthocyanidins and catechins easily sweep free radicals and reduce oxidative stress. Additionally, they can protect vitamin C from oxidation, that way increasing its antioxidant abilities.

Anticancer potential
Cat’s claw extracts are used in the prevention and treatment of serious autoimmune conditions and neoplastic diseases. Tests on patients whose breast cancer was treated with chemotherapy demonstrated that aiding the therapy with cat’s claw extract supplementation helped to reduce some of the negative symptoms. Many patients managed to avoid neutropenia, which is a very common consequence of chemotherapy.

Moreover, clinical tests have shown that cat’s claw extracts directly inhibit the growth of cancerous cell lines in breast, prostate, cervical, and non-small-cell lung cancer. Moreover, they induce the apoptosis (programmed death) of pathological cells.

Antiviral properties
Oxindole alkaloids found in cat’s claw bark exhibit powerful antiviral properties. In vitro tests have shown that they inhibit the replication of the influenza virus type A and combat the herpes virus. They prevent it from infecting cells, that way significantly reducing its ability to spread in the organism.

A test has demonstrated that people with oral herpes who took cat’s claw extracts experienced significantly reduced symptoms of the condition (swelling, red skin, pain) than the group treated with a popular antiviral drug (acyclovir).

To sum up, Cat’s claw is a supplement that efficiently supports the organism’s immunity and can reduce the risk of many serious conditions. It will prove fantastic for people with a weakened immune systems or chronic inflammation. Supplementation can also be considered by people who struggle with recurring viral infections (like resistant herpes).

Cat's Claw (Uncaria Tomentos) is a herb mainly known for its antiviral, anti-inflammatory and antibacterial properties, occurring naturally in the tropical forests of South and Central America. For therapeutic purposes, the bark and root of the plant are used.

Cat’s Claw helps to minimize the symptoms of arthritis (it reduces pain symptoms), demonstrates anticancer effect, optimizes blood pressure (effective in case of hypertension, antithrombotic activity), strengthens the immune system (helpful in case of HIV infection, effective in fighting herpes) and it is also effective in fighting a wide range of digestive disorders (irritable bowel syndrome, stomach and duodenum ulcers, bowel inflammation).

Cat’s Claw may also demonstrate effectiveness in case of borreliosis - it was proven in one of the studies that combining Cat’s Claw and Otoba parvifolia contributed to the destruction of Borrelia spirochetes both in relation to active and inactive forms.
