Maitake is popular for its ability to promote good health and treat a wide variety of diseases.

In particular, some of Maitake mushroom benefits include boosting the immune system’s functioning, helping to lower blood pressure, and fighting cancer cells.

But these are not just tales. Because aside from Maitake’s thousand-of-years-long history of traditional use, there are research studies to back up its amazing medicinal properties.

1. Brief History of Maitake’s Functional Use

For millennia, Hen of the Woods (Maitake) has been used in Japan and China for its nutritional and medicinal properties (1).

1.1 Traditional use of Maitake

Going back, the earliest record of Maitake’s functional use comes from the Shen Nong Ben Cao Jing. It is an ancient book of herbal medicine compiled between 200 BC and 200 AD (2).

In this book, it is stated that Keisho (a type of remedy made with Maitake) can treat various illnesses including stomach problems, hemorrhoids. Also, it improves the spleen, and calms the nerves or mind (3).

1.2 Maitake as adaptogen

Further, traditional Chinese medicine uses Hui Shu Hua (other terms for Maitake) as an adaptogen. Simply, it is a substance that helps the body recover from fatigue and boost the immune response.

Also, ancient records claim that Maitake can stimulate the “qi” (life force). It is said to nourish the spleen, moisten the lungs, and protect the liver (4).

Meanwhile, only in the early 2000s did U.S. researchers become interested in studying Maitake’s alleged medicinal properties.

2. Research-Backed Health Benefits of Maitake Mushroom

In recent years, modern science has begun to confirm what ancient healers already knew. Hen of the Woods mushroom (Maitake) is indeed a powerful medicinal mushroom with a wide range of health benefits.

Here, we list 4 well-established Maitake mushroom health benefits:

2.1. Boosts immune function

Maitake Grifola frondosa beta-glucans support immune health

Maitake mushroom’s health benefits mainly comes from its rich beta-glucans (β-Glucans) content. Simply, β-Glucans are compounds that have been shown to boost immune function and help fight off infections (5).

Besides, Β-glucans are established as effective in activating immune reactions in all species—from earthworms to humans (6).

A 2014 study (Vetvicka, et. al.) shows that orally administered glucans from Maitake strongly stimulate immune defense reactions of animal subjects (7).

2.2. Supports cancer treatment

Maitake Grifola frondosa D-Fraction appears to repress cancer progression

A 2013 study (Masuda, et. al.) suggests that Maitake’s extract called D-Fraction is a useful oral therapeutic. It helps enhance immune function and inhibit tumor growth in patients with cancer (8).

Likewise, a 2016 study (Roldan-Deamicis, et. al.) postulates that the more specific Maitake’s D-Fraction Pro4X can prevent the development of breast cancer in people with a high risk of developing the illness (9 ).

2.3. Regulates blood sugar levels

Maitake Grifola frondosa SF-Fraction or SFX supports healthy insulin function for diabetics

Maitake’s fruiting bodies contain healthy compounds that can help to regulate blood sugar levels. This is especially helpful for people with diabetes or pre-diabetes.

As shown in a 2012 study (Preuss, et. al.), Maitake’s bioactive glycoprotein called SXfraction (SFX) may be useful for treating disturbances in glucose and insulin metabolism. Also, SFX helps with elevated BP in type-1 diabetes (10).

In addition, a more recent study in 2020 (Konno) shows that SFX shows promise for the novel treatment of type 2 diabetes. It also appears to be a safe, natural agent in improving diabetic conditions (11).

2.4. Lowers bad cholesterol

Maitake Grifola frondosa beta-glucans can reduce LDL (bad) cholesterol and support heart health

A 2021 study (Fukushima, et. al.) suggests that Maitake’s fiber significantly lowers the cholesterol level (12). Consequently, it improves overall cardiovascular health to lower your risk for heart disease.

Likewise, an earlier study in 2013 (Sato, et. al.) shows that dietary Maitake can prevent and improve the symptoms of obesity, diabetes, and arteriosclerosis (13).
