While reishi mushrooms have gained attention recently, these fantastic fungi have been used for centuries in traditional medicine for their health-promoting properties. 

What Are Reishi Mushrooms?
Reishi mushrooms, scientifically known as Ganoderma lucidum, have a history that spans centuries and continents. Revered in traditional Chinese medicine as the "mushroom of immortality," these fungi are renowned for their potential health benefits. Reishi mushrooms belong to the polypore family, characterized by their unique growth on trees and logs. They have a distinct appearance with a reddish-brown cap and a glossy surface.

Health Benefits of Reishi Mushrooms:

Boost the Immune System:

One of the most important effects of the reishi mushroom is that it can boost your immune system. While some details are still uncertain, test-tube studies have shown that reishi can affect the genes in white blood cells, which are critical parts of your immune system.

What’s more, these older studies have found that some forms of reishi may alter inflammation pathways in white blood cells 

One 2006 study found that reishi could increase the number of other white blood cells in those with colorectal cancer.

In another older study, the fungus improved the function of lymphocytes, which help fight infections and cancer, in athletes exposed to stressful conditions

Anti-Cancer Properties:

Many people consume reishi due to its potential anticancer properties In fact, several test-tube studies have shown that it can lead to the death of cancer cells.

Some research has also investigated if reishi could be beneficial for prostate and colorectal cancer due to its effects on inflammation and certain signaling pathways involved in cancer development.

What’s more, one review indicated that the mushroom could benefit people with cancer when used alongside traditional treatment by increasing the activity of white blood cells and improving quality of life.

Could reduce Fatigue and Depression:

Though reishi’s effects on the immune system are often most emphasized, it may also reduce depression and fatigue.

One older study examined its effects in 132 people with neurasthenia, a condition associated with aches, pains, dizziness, headaches, and irritability. The researchers found that fatigue was reduced and well-being was improved after 8 weeks of taking the supplements.

Another 2012 study on people with breast cancer found that taking reishi powder reduced fatigue, anxiety, and depression and improved quality of life after 4 weeks.

Heart Health and Blood Sugar:

A number of studies looking at people with both healthy and unhealthy levels of blood sugar and lipids found that reishi mushroom may help decrease blood sugar, increase HDL (good) cholesterol, and decrease triglycerides. 

At least one older study in healthy adults showed a slight trend toward lower lipid levels.

Additionally, some other studies have found no effect of reishi supplementation on cholesterol or triglyceride levels. Meanwhile, some older animal and human studies also suggest that certain compounds found in the reishi mushroom could decrease blood sugar.

Improves Sleep:

Scientific research suggests that the Reishi mushroom does indeed have potential sleep-enhancing benefits. One study found that Reishi increased total sleep time and non-REM time in rats. Another study found that Reishi increased sleep time in mice. Many other studies indicate a link between Reishi and improved sleep.

Antioxidant status:

Antioxidants are molecules that can help protect cells against damage. Many claim that reishi mushroom is effective at improving antioxidant status.
