Since time immemorial mushrooms have been consumed not only as a source of food but also for medicinal purposes. Pharaohs ate mushrooms as a delicacy, Greeks believed them to be a source of divine strength and the Chinese treasured them for building endurance in their athletes. Described as nature’s Umbrella’s, mushrooms are a treasure trove of many vital nutrients, minerals and bioactive compounds which clearly build immunity and provide a host of health benefits. Mushrooms are also probiotic (Helps the body strengthen itself & fight off illness).
The concept of Modern Medicine is based on Prophylactic measures which in simple terms means, prevention is better than cure. To this end, the proteins in edible mushrooms act as powerful immune boosters and disease fighters. Mushroom intake helps the body strengthen its defense system and fight off illness by maintaining a high level of antibodies and at times act as antibiotics. Senior citizens, especially men are likely to suffer from a drop in their blood selenium. Including mushrooms in their diet will take care of the deficiency. Selenium in mushrooms is very effective in inhibiting cancerous cells too.
The vitamin B complex, comprising of riboflavin, niacin and pantothenic acid is essential for the proper functioning of the digestive and nervous systems. A small serving of white mushrooms is enough to meet the body’s daily requirement. In addition mushrooms are known to regulate the blood pressure level and maintain the right balance of water in fat and muscle tissues. Moreover, the high lean protein content in mushrooms helps burn cholesterol when they are digested.
Even though, the role of mushrooms in food and medicine was known for thousands of years, it’s only off late that mushrooms are gaining popularity as a health food. Most edible mushrooms are low in calories and carbohydrates; provide essential amino acids, important vitamins and minerals including vitamin B, iron, potassium, selenium and zinc.
Mushrooms and Immune systems:
Most of the research completed on the health benefits of mushrooms has focused on four types of medicinal mushrooms, namely Maitake, Shiitake, Crimini and Reishi. The Maitake and Shiitake types of mushrooms are commercially cultivated in North India, but are expensive.
For the common man, the good news is that the commonly available and affordable button mushroom (Agaricus bisporus) is known to fight off different types of cancer, lower cholesterol, fight off inflammatory diseases, and prevent chronic diseases due to the presence of powerful antioxidants like ergothioneine. Other naturally occurring biological compounds contribute towards antitumor property. The compounds present in mushrooms (polysaccharides and glycoprotein’s) activate a variety of host specific immune responses.
Maitake is known to prevent diabetes, enhance immunity, support cardiovascular health and inhibit few types of cancer. Shitake mushroom plays an active role in treating liver ailments, preventing heart disease and combating AIDS. Reishi mushroom is helpful in lowering the risk of Asthma. Crimini mushrooms play an important role in the prevention of fatigue and are specially known to inhibit breast cancer.
In the last two decades there has been a rise on the use of mushrooms as nutraceuticals and many edible species have been thoroughly investigated and authenticated for medicinal use. The species that have been properly analyzed for medicinal value are: Ganoderma lucidum (Reishi), Lentinus edodes (Shiitake), Grifola frondosa (Maitake), Agaricus blazei (Hime-matsutake), Cordyceps militaris (Caterpillar fungus), Pleurotus ostreatus (Oyster mushroom) and Hericium erinaceous (Lions mane).

The rapid advancement in science and technology has helped scientists isolate the biologically active ingredients present in mushrooms that are responsible for their healing properties. Today modern medicine has clearly recogonized the role of medicinal mushrooms in lowering the risk of cancer, promoting the immune function, ward off pathogenic strains of microorganisms, boost heart health, combat allergies, help balance blood sugar levels, detoxify the toxins produced in the body, enhance the oxygen flow to the blood vessels and help the brain retain a state of alertness.

Identification & care to be taken while picking and consuming wild mushrooms:
During our treks we have collected various mushroom species and have sent them to laboratories for identification. Mushrooms are present in all environments but their numbers are dwindling in rainforests. Throughout the world, over 38,000 varieties of mushrooms have been discovered, only about 3,000 are edible, about 700 have known medicinal properties, and less than one percent are recognized as poisonous, and only a select few are commercially grown on farms. The risk involved in collecting and eating poisonous mushrooms include nausea, swelling, sweating, cramps, diarrhea, vomiting, convulsions, and hallucinations and in some cases a mortality rate of 60 % or more. People with expertise in mycology should attempt to collect mushrooms from the wild since some varieties are toxic.
