Better sleep at night

‘My friend suggested taking reishi from Sacred Source Botanicals for better sleep, I’m so glad I followed her advice. My sleep is much deeper, I wake up less often at night and if I do, I fall right back to sleep. I feel much more refreshed when I wake up the next morning. Really good stuff!’

Reishi is a fungus and also goes by its Latin name ‘Ganoderma lucidum’. Due to its extraordinary health properties this medicinal mushroom has been called ‘Mushroom of Immortality’ or ‘Queen of Mushrooms’’ for thousands of years by Traditional Chinese Medicine practitioners.

Reishi mushroom extract has been used for thousands of years in Chinese medicine for regulating a healthy immune response, to combat certain viral infections, to help improve chronic lung conditions, to normalize high blood pressure and high cholesterol, and to reduce stress and prevent fatigue. In addition it has been used to support liver function, digestion, healthy sleep patterns, cardio-vascular health and healthy inflammation response. It is also known as a strong antioxidant and adaptogen.

Reishi that is grown on Duonwood (as opposed to grains) is best since that is the way it produces triterpenes. As for different species or varieties, it is hard to say if anyone is better than any others.

Reishi has a rather earthy taste and due its active compound triterpenoid can be quite bitter. If a reishi mushroom product is not bitter, it may indicate inferior quality.

Anyone who wants to be healthier overall. It is great for many different facets of the immune system, oxidation and anti-aging. However, if a medical condition is present, a qualified health care practitioner needs to be consulted before taking reishi supplements.


Yes, it is USDA organic certified.

Our reishi is grown on Duanwood.

No. There are no grains involved in our reishi mushroom growing process.

Due to our high quality commitment, our reishi extracts are made from reishi fruiting bodies only. There are numerous other suppliers in the market who make their reishi extract from reishi mycelium grown on grain, which typically tests for significantly lower medicinal value.

Our reishi extract is made through hot water extraction. This is in our experience the most effective extraction method. The extraction ratio for our reishi extract is 15:1.

We don’t test specifically for polysaccharides because this is a large category of different things.

Many companies talk about the high polysaccharide levels of their products. Why? Because mushrooms can have medicinal compounds that are polysaccharides, such as beta-D-glucan, PSK (polysaccharide krestin) and PSP (polysaccharide peptide). However, a high polysaccharide level does not necessarily translate to high levels of the aforementioned medicinal compounds. Polysaccharides can also be found in grains and vegetables – starch and cellulose are polysaccharides, as well.

In order to ensure high potency of your mushroom product, look for the (1-3, 1-6) beta-D-glucan, not for polysaccharides.

All our medicinal mushroom extracts are tested by a third party lab (Megazyme) for their beta-D-glucan levels to ensure high potency. More specifically, we test for the (1-3, 1-6) beta-D-glucans, which are the sought after medicinal compounds in most medicinal mushrooms.

The main active medicinal compounds in reishi are generally considered beta-D-glucans and triterpenoids. In addition, there are numerous other beneficial phytochemicals.

Our reishi regularly tests at 20% or higher.

Our reishi regularly tests at 4% or higher.

When it comes to sourcing our reishi mushrooms, quality and safety are of foremost concern. In order to yield the quality and medicinal potency reishi mushrooms are famous for we turned to the place where growing and extraction methods have been continuously refined for the past centuries: China.

Our reishi mushroom is traditionally and organically grown on a USDA organic certified farm in an eco-village in China. As it stands, China is the best place to get the actual mushroom fruiting bodies of reishi grown on duanwood, rather than mycelium on grain, which is mostly found in US grown medicinal mushroom products.

We regularly test for the potency of our mushrooms, including our reishi extracts. In addition we test for any traces of heavy metals or other contaminants. This ensures quality and safety of our reishi extracts.

Yes. As we, the Sacred Source Botanicals team, are also consuming our products on a daily basis, we are always concerned about the health and safety of our products.

We get our reishi mushrooms consistently tested by third party laboratories. All of our product specifications follow the following industry established limits:

  • Lead: < 2ppm*
  • Arsenic: < 2ppm*
  • Cadmium: < 2ppm*
  • Mercury: < 0.1ppm*

*ppm = parts per million

Reishi mushrooms like other medicinal mushrooms have to be extracted in order to make the medicinal compounds bio-available. In its raw form, reishi may have some benefits, as well. However, the medicinal properties reishi is famous for are locked away in the mushrooms cell-walls, unless it gets extracted for example through hot water extraction.

No, it is just pure reishi mushroom extract powder. No added fillers, starch, binders or any other additives.

How to Take Reishi

Our reishi extract dissolves in both cold and hot water. Sometimes it clumps a little bit, but if stirred this will dissolve completely, especially if added to hot water.

With our extract you’ll just add the dose ½ tsp to hot water and stir. See our recipe section for more inspiration.

Our recommended dose is 1,000mg 1-3 times daily. 1,000 is equal to ½ teaspoon of extract powder. For some a larger dosage is safe, as well. However, If you have a medical condition or are pregnant, please consult a qualified health care practitioner before taking reishi supplements.

Most of our customers like to take their reishi extract at night as a sleep aid due to its calming effect. However, it is not sedative and you can take reishi extract at any time of the day on an empty stomach as well as before, during or after meals.

Reishi can be taken at any time even if one is not showing any symptoms of compromised health. The aim of medicinal mushrooms is to support your body when you are healthy so you don’t get sick in the first place.

Side Effects and Contraindications

Because there isn’t enough scientific data to back up safety in young children, it is best for young children to avoid reishi mushrooms. If you nevertheless would like to give your child a reishi extract, please consult a pediatrician or qualified healthcare practitioner before taking the supplement.

Because there isn’t enough scientific studies involving pregnant or breastfeeding women, it is best for nursing or expecting women to avoid reishi. If you nevertheless would like to take reishi extracts, it is very important to consult a qualified health care practitioner before taking reishi supplements.

Yes, absolutely. However, if your pet has a medical condition, please consult a veterinarian first.

Because it is untested as such children, pregnant or breastfeeding women may want to avoid reishi. Anyone who has a medical condition, needs to consult a qualified health care practitioner before taking reishi supplements.

Reishi may interact with anticoagulants and antihypertensives. If you are taking any medications, be sure to consult with your physician or qualified healthcare practitioner to discuss any adverse interactions.

One of the most important effects of the reishi mushroom is that it can boost your immune system (Show Study).

What’s more, these studies have found that some forms of reishi may alter inflammation pathways in white blood cells (Show Study).

Research in cancer patients has shown that some of the molecules found in the mushroom can increase the activity of a type of white blood cell called natural killer cells (Show Study).

Natural killer cells fight infections and cancer in the body (Show Study).

Another study found that reishi can increase the number of other white blood cells (lymphocytes) in those with colorectal cancer (Show Study).

Although most immune system benefits of reishi mushroom have been seen in those who are ill, some evidence has shown that it can help healthy people, too.

In one study, the fungus improved lymphocyte function, which helps fight infections and cancer, in athletes exposed to stressful conditions (Show Study1,Show Study2).

Reishi mushrooms are considered natural antiviral, antibacterial and antifungal substances thanks to the active compounds that they contain. For example, aside from relieving allergies, triterpenes offer protection against microbial, viral and fungal infections.

Triterpenes can be found in many plant foods that taste somewhat bitter, a sign that they’re protective in nature and defend the plant against predators. (Show Study1)

Because reishi mushrooms can improve blood circulation and lower inflammation, they can help resolve infections more quickly, reduce pain and fight fatigue.

Reishi mushrooms have been used to help treat symptoms and underlying causes of urinary tract infections, hepatitis and even HIV/AIDS. (Show Study2, Show Study3)

According to a study of 61 patients with gum disease testing positive for oral HPV, 88% of the 41 patients who received both turkey tail and reishi mushrooms showed positive results after only two months of treatment. (Show Study4, Show Study5)

Many people consume this fungus due to its potential cancer-fighting properties (Source,Show Study).

In fact, one study of over 4,000 breast cancer survivors found that around 59% consumed reishi mushroom (Show Study).

Additionally, several test-tube studies have shown that reishi extract can lead to the death of cancer cells (Show Study1,Show Study2,Show Study3).

Reishi mushroom has also been studied for its role in preventing or fighting colorectal cancer (Show Study1,Show Study2).

Some research showed that one year of treatment with reishi decreased the number and size of tumors in the large intestine (Show Study).

What’s more, a detailed report of multiple studies indicated that the mushroom can beneficially affect cancer patients (Show Study).

These benefits included increasing the activity of the body’s white blood cells, which help fight cancer, and improving quality of life in cancer patients.

However, researchers state that reishi should be administered in combination with traditional treatment rather than replacing it (Show Study).

Reishi’s effects on the immune system are often most emphasized, but it has other potential advantages as well.

These include reduced fatigue and depression, as well as improved quality of life.

One study examined its effects in 132 people with neurasthenia, a condition associated with aches, pains, dizziness, headaches and irritability (Show Study).

The researchers found that fatigue was reduced and well-being was improved after 8 weeks of taking the supplements.

Another study found that fatigue was reduced and quality of life was improved after 4 weeks of taking reishi extract powder in a group of 48 breast cancer survivors (Show Study).

In addition, the people in the study also experienced less anxiety and depression.

Reishi mushrooms work as adaptogens. They can help your body cope with stress more efficiently and help regulate hormone levels to optimize your health.

Some studies indicate that reishi mushroom extract could help normalize levels of certain receptor hormones, which may be beneficial in the treatment of cancer. (Show Study1)

Other studies show that it can protect and positively impact the endocrine system, which encompasses the glands throughout the body that are responsible for the production of hormones.

This could have far-reaching effects on many aspects of health, as the endocrine system has a direct impact on metabolism, growth, sleep, mood and sexual function. (Show Study2)

When consumed in continuous, small doses, reishi may help to support the body’s sleep cycles (Source).

The triterpenes found in the reishi mushroom may have blood pressure-lowering abilities as well as benefits for blood-clotting and cholesterol. This is likely because they help lower inflammation within blood vessels and arteries while also restoring hormonal balance. (Show Study1)

High blood pressure and high cholesterol can sometimes be caused by hormonal issues, including thyroid disorders or high amounts of stress. Reishi mushrooms help restore optimal hormonal levels to strengthen the cardiovascular system. (Show Study2, Show Study3)

In addition to lowering blood pressure, reishi mushroom extract can improve overall circulation, lower inflammation that worsens heart problems and prevent clogged arteries by keeping cholesterol under control. (Show Study4)

One 12-week study of 26 people showed that reishi mushroom may increase “good” HDL cholesterol and decrease triglycerides and as a result improve cardiovascular health (Show Study5).

The liver is one of the most vital organs in the body. It is responsible for aiding in detoxification and helping clean, process, store and circulate healthy blood and nutrients.

Reishi mushrooms work as adaptogens to help improve liver function and prevent liver disease. They allow your body to flush out toxins and bacteria more efficiently and improve immunity against diseases that can develop over time.

A 2013 study published in the International Journal of Medicinal Mushrooms found that reishi induces hepatoprotective effects on acute liver injury because it contains antioxidant properties and fights harmful immune responses that slow down liver function. (Show Study)

Sustaining high levels of blood sugar can bring detrimental effects to overall health, causing symptoms like fatigue, unintentional weight loss and frequent urination. Some research shows that reishi mushrooms may have anti-diabetic properties, helping to maintain normal blood sugar levels to prevent adverse side effects.

For example, studies showed that reishi mushrooms were able to decrease levels of both blood sugar and insulin in mice. They also helped modify levels of certain enzymes involved in blood sugar control and improved the way that the body uses insulin to transport sugar from the bloodstream to the tissues to be used as fuel. (Show Study1, Show Study2, Show Study3)

Some preliminary research in humans reported similar findings (Source).

Triterpenes are active ingredients in reishi mushrooms. They are a type of ganoderic acid tied to a reduction in allergies and histamine reactions associated with asthma. For this reason, the reishi mushroom is often used as a safe and effective asthma natural remedy. (Show Study1)

Triterpenes are capable of lowering allergic reactions because of the way they affect the immune system, strengthen the digestive organs, protect the gut lining, lower inflammation, inhibit a histamine release, improve oxygen utilization and improve liver functions. (Show Study2)

Antioxidants are molecules that can help prevent damage to your cells (31).

Because of this important function, there is substantial interest in foods and supplements that can enhance antioxidant status in the body.

Reishi’s antioxidant properties are the important foundation of its immune-boosting benefits.

Several studies show that extracts of reishi mushroom can protect against oxidative stress, even in severe cases. (Show Study1, Show Study2, Show Study3)

Oxidative stress is caused by free radicals. These “free radicals” are rogue cells that cause chronic inflammation. If this type of inflammation is left unchecked, it can lead to a wide range of diseases and health problems.

Antioxidants play an important role in anti-aging, clearing brain fog, apoptosis (important function in fighting cancer), promoting healthy inflammatory response, etc.

Reishi or Ganoderma lingzhi, has been recorded for its use for around 2000 years especially in Eastern medicine. (Show Study1, Show Study2).

Most notably used in China by Taoist monks to promote calmness, as well as enhance their meditative practices. It has even been used by Chinese royalty who sought longevity and held reishi or “the mushroom of immortality” in high esteem. Reishi was listed the most cherished among the superior herbs, that are considered to prolong life, prevent aging, boost qi, and make the body light.
