The History of Reishi

Reishi’s benefits have been reaped for thousands of years, and the much-loved medicinal mushroom is mentioned in many ancient scriptures and texts. One of the oldest uses of reishi is recorded in the Shen Nong Ben Cao Jing, an extensive herbal handbook which provides information on the benefits of a range of mineral and botanical substances. The book is still highly regarded today, and it is commonly referred to by Traditional Chinese Medicine practitioners around the world.

Reishi’s historical importance is also reflected in a range of ancient artifacts. This striking mushroom has been embroidered onto silk robes worn by royalty, painted and sculpted, and it was often used as a symbol to depict longevity and spiritual development.

Reishi Nutritional Profile

Over 36 nutritional compounds have been identified in reishi mushroom. It has an extremely high polysaccharide content, plus it’s rich in beta-glucans, triterpenes, antioxidants, ganaddoral, luceidenic acid B, live enzymes, langston, coumarins and ergosterol. Reishi contains several minerals including potassium, magnesium and calcium.  

The exact amount of each compound present in the reishi mushroom depends on a range of factors including the growing conditions, the age of the mushroom and its species or strain. Typically, a reishi mushroom is around 90% water, while the other 10% is made up of protein, fats, carbohydrates and fibre.

Reishi for Immune Support

From lowering blood pressure to helping to alleviate allergies, reishi has a whole host of health benefits, yet it’s most famous for its powerful immune-enhancing properties. Several scientific studies reveal that the polysaccharides present in reishi mushroom (as well as in several other species of medicinal mushrooms) are able to naturally increase the production of T-cells and macrophages. The beta-glucans in reishi act as immune modulators and help to fight off harmful invaders, while canthaxanthin displays promising anti-tumor potential.

As well as immune support, reishi also shows anti-inflammatory qualities. Researchers at the University of Texas Health and Science Center discovered that one dose of reishi displays the same anti-inflammatory effects as five milligrams of hydrocortisone.

Reishi: A Spiritually Potent Medicinal Mushroom

Monks, yogis and other spiritual seekers take reishi mushroom supplements in order to help them along their spiritual path. It is said that reishi mushrooms help to induce feelings of calm and peace, plus they can increase focus and concentration which is beneficial for long periods of meditation. Reishi can also be used as study tool to help to enhance memory and calm nerves before taking a test.

In Chinese, the term lingzhi loosely translates as the essence of immortality, and the mushrooms are said to enhance well-being, longevity and spiritual power. In Traditional Chinese Medicine, reishi is said to increase the flow of the three treasures: jing, qi and shen. Shen is a subtle yang energy which is believed to help us to stay balanced, centered and calm.

Reishi to Reduce Stress and Anxiety

This potent medicinal mushroom is one of only 16 recorded substances to be classified as having adaptogenic qualities. Adaptogens were first coined by the Russian pharmacologist Lazarev, who defined them as “agents which help an organism to counteract any adverse effects of a physical, chemical or biological stressors by generating nonspecific resistance”. In other words, adaptogens are ‘wise’ substances which work with the body to improve its current state of health. They can help to normalize the body's functions, recharge the adrenal glands, naturally lower stress levels and reduce anxiety.

How to Use Reishi

Reishi mushrooms require a lot of care and preparation to transform them into a palatable and digestible supplements. Slices of raw reishi need to be cleaned, boiled in water, stewed and strained in order to create a tonic tea. Luckily, nowadays you can purchase pre-a prepared reishi powder; reishi is also available in capsule, tablet and tincture forms.

You can dissolve reishi powder into warm water to make a tonic tea, or blend it into smoothies, juices and shakes. You’re probably thinking, what does reishi taste like? Well, it does have a distinct earthy and bitter taste, which can be masked with other herbs, spices or natural sweeteners. Many people find that they become accustomed to the taste of reishi over time. You can also buy medicinal mushroom complex powders which consist of several different species of mushrooms such as chaga, turkey tail, tremella and maitake, for a more potent blend with a milder taste.

Reishi isn't limited to being used in beverages, as it can also be used in a range of foods including sauces, soups, dressings, raw chocolates, cakes, protein balls and bars, and much more.

Reishi Dosage and Side Effects

If it’s your first time taking reishi supplements, then it’s a wise idea to start small and gradually increase your dosage. Begin by taking less than half a teaspoon, and then slowly up your intake to a whole teaspoon of reishi powder if required. Traditional Chinese Medicine practitioners may prescribe larger doses for people suffering from chronic illnesses.

The American Herbal Pharmacopoeia states that reishi is safe to ingest, and there are no severe reported side effects. However, this mushroom can be particularly potent, and on rare occasions it may cause a dry mouth, dizziness or stomach aches. Lower your dose or contact your healthcare provider if you experience any of these reishi side effects.

Reishi Recipes

An increasing number of juice bars, health stores and health-conscious chefs are using reishi recipes. The most common way to use it is to make a plain tonic tea. However, you can add a splash of your favourite nut or coconut milk, along with a dash of cinnamon and your sweetener of choice for a warming creamy reishi tea. You can also experiment with adding different medicinal mushrooms such as chaga, tremella, turkey tail or other tonic herbs and spices to make an ultra-nourishing superfood elixir.

Reishi coffee is also becoming increasingly popular, as coffee pairs well with reishi’s strong flavour. Just make your coffee the way that you prefer it, then add in 1/2 to 1 teaspoon of reishi powder and stir until it dissolves. A top tip is to blend in a teaspoon of virgin coconut oil to create a creamy vegan-friendly bulletproof-style reishi coffee. If you want to get the same pick-me-up without the jitters that are associated with caffeine, then you may want to try making tonic teas with energy-enhancing superfoods such as pine pollen or ginseng.

The famous mycologist, Paul Stamets, said that “reishi stands out as one the most valuable of all polypore mushrooms in nature for the benefit of our health”. With its incredible health benefits, reishi is sure to make an excellent addition into any diet.
