Mushrooms have been used in folk medicines for thousands of years
Mushrooms are an integral part of the ecosystem and have been used in folk medicines for thousands of years. Our ancestors have used mushrooms as medicine since ancient times. For example, the Greek physician Hippocrates, circa 450 BCE, classified the amadou mushroom as a potent anti-inflammatory and for cauterizing wounds. The alchemist Tao Hongjing, from the 5th century, described several medicinal mushrooms, including ling zhi and zhu ling, some of which were reportedly used by Shennong many centuries earlier. Ötzi, the Ice Man, who lived nearly 5300 years ago, carried amadou and a birch polypore in a pouch to help him survive in the Alps of northern Italy. The First Peoples of North America used puffball mushrooms as wound healers.
Mushrooms are nature’s miniature pharmaceutical factories, rich in a wide array of novel constituents and active metabolites. They are a source of biologically active compounds with medicinal values. They have been used as hepatoprotective agents, immune-potentiating agents, complementary medicines, and dietary supplements for anticancer and antiviral purposes. Recent studies have also focused on the therapeutic and health benefits of the specific bioactive nutraceuticals of mushrooms, such as antitumor, antibacterial, antioxidant, antiallergic, immunomodulating, cardiovascular protection, detoxification, antiviral, antifungal, antiparasitic, immune function enhancement, antioxidant, anti-inflammation, hepatoprotective, hypolipidemic, antithrombotic, antidiabetic, hypotensive, antiproliferative, anti-HIV, hypo-cholesterolemic, anticancer, cytotoxic, and anticoagulant activities.
Mushrooms also have the ability to attenuate the health hazards induced by obesity and impaired functions caused by ageing. They are recommended to heart patients due to their high protein and low-calorie values, and their essential amino acids are required by adults to keep healthy. They also contain valuable minerals like copper, phosphorus, iron, potassium, and calcium.
The recent development of the MALDI-TOF MS technique, which is used for the rapid, cost-effective, and high-throughput identification of fungi, has further increased interest in medicinal mushrooms. However, it is important to note that mushroom dietary supplements often lack sufficient scientific evidence for safety or effectiveness, and quality can vary due to inconsistent processing and labelling.

Mushrooms have therapeutic and health benefits
Mushrooms have been consumed by humans for centuries due to their ease of cultivation and multiple functional activities. They are a good source of vitamins, minerals, and antioxidants, and have unique therapeutic and health benefits.
Mushrooms are nutrient-dense and low in calories, making them a healthy food option. They contain essential amino acids required by adults to stay healthy, and their high protein content makes them ideal for heart patients. They are also rich in potassium, low in sodium, and contain valuable minerals such as copper, phosphorus, iron, and calcium.
The polysaccharides in mushrooms, their most abundant carbohydrate, stimulate the growth of healthy bacteria in the gut. Unlike other foods that break down with stomach acid, these polysaccharides pass through the gut unchanged, encouraging the growth of good bacteria. Mushrooms also contain macronutrients that support a healthy immune system, such as selenium, vitamin D, and vitamin B6.
In addition to their nutritional benefits, mushrooms possess medicinal properties due to their diverse secondary compounds and metabolites. They have been used in folk medicine for thousands of years and are now widely employed as dietary supplements, especially in complementary alternative medicine (CAM) and complementary integrated medicine (CIM). The medicinal properties of mushrooms include anti-inflammatory, antibacterial, antiviral, and antioxidant activities, among others.
Research also suggests that consuming mushrooms may have cognitive benefits. Studies have found that eating more than two cups of mushrooms per week is associated with a 50% lower risk of developing mild cognitive impairment (MCI), a precursor to Alzheimer's disease. Certain mushroom varieties, such as Cordyceps, Turkey Tail, and Lion's Mane, are believed to have extra brain-boosting benefits due to their higher bioactive nutrient content.
Overall, mushrooms offer a wide range of therapeutic and health benefits that have been recognized and utilized by various cultures throughout history. While the Western medical community has been slower to incorporate mushrooms into conventional therapeutic practices, there is a growing interest in mycotherapy and ongoing research into the potential benefits of these fascinating fungi.
