The Secrets of Reishi Mushroom

Where it began

Reishi has been used for thousands of years to heal, improve health, and promote general longevity. The use of this mushroom began with Chinese emperor Shen Nong, who tasted and cataloged over 365 plants to create the first book of Traditional Chinese Medicine (8). Each plant was evaluated on their treatment capabilities, effectiveness, and the possibility of side effects. This led red reishi mushroom to be classified as a "Superior" plant for medicinal use. Reishi has only increased in popularity since that time and is now one of the most widely used medicinal mushrooms (5).

Traditional Use

It is no question why Reishi has been referred to as the "Mushroom of Immortality". Throughout history they have been used for liver problems, heart conditions, asthma, high blood pressure, arthritis, potential treatment for tumor growth, and even an effective skincare ingredient! (1, 5, 6, 7)  Though the list is impressive, many of these claims tie back to the anti-inflammatory and immune boosting properties of the fungus.

Anti- Inflammatory 

Asthma, for example, is caused by an inflammation of the airways, as well as bronchitis being an inflammation of the bronchial tubes in the lungs (9). Arthritis again is an inflammation of the joints. Reishi has shown beneficial to these ailments because of decreased inflammation.

Skincare

Skin soothing is also linked to inflammation. Reishi has been used to heal, calm, and reduce redness in the skin because of this property (10). It has also been shown to have skin lightening capabilities as it has been shown to inhibit tyrosinase, which is the enzyme responsible for the production of dark spots (3). Because of this, the main skincare claims to reishi are calming and brightening the skin.  

Blood Pressure 

Reishi’s most notable behavior, besides the inflammation assist, is its ability to potentially lower blood pressure. This leads to improved circulation and decreased risk of heart disease. The main goal when treating chronic high blood pressure or hypertension is to bring blood pressure back into a normal range (5). Most studies agree that reishi mushroom can help to increase blood flow, but some expand to lowered cholesterol, increased white blood cell count, and overall better circulation through the heart (1, 5, 7).

Sleep 

If that isn't enough, reishi also has sleep boosting abilities. Chinese and Japanese herbalists have been using this mushroom to treat insomnia for centuries (2, 5). Some have found that this sleep promotion is due to a reduction in stress related to sleep quality, others observe a calming effect on the central nervous system helping to relax the muscles and ease the transition into sleep(2, 5, 7). Either way, Reishi has shown to help with the preliminary stages of sleep, but has no notable effect on the quality of sleep or the REM cycle (4). Reishi is a good place to start for those that have trouble falling asleep but do not have problems with sleep quality but can be combined with another sleep aid like Wulinshen mushroom that could lead to deeper more restful sleep.


Overall, through the listed studies, reishi has been found to decrease inflammation, improve blood flow, and can be a useful sleep aid. As always please consult a physician if considering use and if you have any pre-existing conditions.
