New Product: Turkey Tail capsules! The low down.
Plenty of you asked for it, and we're stoked to deliver! Introducing to the Flow State family: Turkey Tail mushroom extract capsules!
Turkey Tail (Tramates versicolor) has been on a few of your minds after watching the Fantastic Fungi documentary (highly recommend), or after watching the Paul Stamets TED Talk where he discusses his mother's breast cancer, and the incredible results of a full remission using Turkey Tail (link here).
A brief run down:
Tramates versicolor received its name due to the multi-coloured (hence-versicolor) concentric circles on this fruited body.
Turkey tail is most likely the easiest mushroom to forage in nature, as it can be found almost anywhere! Despite its prolific presence in most forests, it is not edible in its raw/natural form! It must undergo an extraction process to be ingested and absorbed.
It is said the ancient Taoists were astonished by the abundance of turkey tail on pine trees, which was notoriously anti-fungal. They concluded that a mushroom of such tenacity must contain incredible medicinal properties, and hence it was explored as a medicinal fungus.
Getting into the nitty-gritty:
Like other functional mushrooms, turkey tail mushrooms are adaptogens. As their name suggests, adaptogens help the body adapt to the various types of stressors we may come across. This includes physical, biological, or chemical stressors. Adaptogens interact with the hypothalamic-pituitary-adrenal (HPA) axis to help stabilize your cortisol levels under stress and assist the body in reaching balance again.
There is good reason why this mushroom has been popping up everywhere. According to the entry for yún zhī in the Bencao Gangmu (Compendium of Materia Medica) by Li ShiZhen, the fungus provided 'health and long life benefits if consumed regularly'. A few of the noted benefits include removing toxins, increasing energy, strengthening the immune system, and supporting liver and spleen function (1).
In conventional medicine, turkey tail has been used to support the immune systems of people with weakened immunity (2). Research conducted in vitro suggests turkey tail has strong antioxidant properties and may protect DNA from free radical damage (2).
Preclinical studies show that polysaccharides from turkey tail can induce proliferation of both T and B cells, bolstering both our innate and adaptive immune responses (3,4,5).
Turkey tail is full of polysaccharides and triterpenes (forms of long chain carbohydrates with several functions for human cells). What makes turkey tail unique is two unique beta glucan polysaccharides- polysaccharide krestin (PSK) and polysaccharide peptide (PSP). So far, over 45 independent PSP-related preclinical and clinical studies have been conducted. Furthermore, the China State Food and Drug Administration has also approved 13 types of products based on the turkey tail mushroom (6).
PSK is known for its anti-cancer properties, and both PSK and PSP have the ability to regenerate white blood cells and stimulate the creation of immune T-cells and killer cells- enabling the immune system to step into ultimate badassery and ward off and destroy foreign pathogens.
In 1977, the Japanese Ministry of Health approved PSK for clinical use. It has since been extensively studied for its role in supporting immune system health in a variety of situations (7,8,9). Today, it is the best-selling anti-cancer drug on the market in Japan.
Turkey tail is also an excellent source of antioxidants (contain 35 different phenolic compounds).
