I’ve been using medicinal mushrooms in my clinical practice for over a decade so I want to share with you my favorite top 5 medicinal mushrooms and how they can benefit your health. Mushrooms have been used for medicinal purposes for thousands of years and there is a long tradition of using them in Asia. Medicinal mushrooms are now a popular research topic for scientists and they‘ve become very popular in the last few decades in the western world. Formerly, medicinal mushrooms were only picked wild and some of them were rare and very valuable. Now, however, medicinal mushrooms are produced in enormous quantities each year to be used as food supplements. In this article I‘ll discuss the five types of mushrooms I use the most in my clinic, but all of them have in common that they strengthen the immune system. They‘ve also been known to impair the growth of cancer cells and are being used in cancer treatments.

Turkey Tail Mushrooms

Most research has been done on the Turkey Tail mushroom ((Trametes versicolor) out of all the medicinal mushrooms. Big clinical trials have been done on the active ingredients PSK (Krestin) and PSP (Polysaccharide Peptide) which have shown very positive results in relation to many types of cancer, for example, stomach cancer, lung cancer, breast cancer and colon cancer. The Turkey Tail mushroom is also anti-viral and studies have shown its powers against herpes and HIV viruses.

Reishi Mushrooms

In China, the Reishi mushroom (Ganoderma lucidum) was believed to increase longevity, but it was rare so only the emperor and his court could enjoy its benefits. In Japan, the use of Reishi concurrently with other cancer treatments is approved by the Japanese Ministry of Health. The Reishi mushroom is believed to increase the effectiveness of traditional chemotherapy and decrease its side effects. Reishi is also believed to have a balancing effect on the immune system and has been used against auto-immune diseases.
