It’s important to note that while Ganoderma has a long history of traditional use and many potential health benefits, more rigorous scientific research is needed to confirm and fully understand its mechanisms of action. Additionally, the use of Ganoderma supplements should be discussed with a healthcare professional, especially if you have underlying health conditions or are taking other medications, as it can interact with certain drugs.

Possible Dangers and Side Effects

While ganoderma is generally considered safe for most people, it’s important to be aware of potential dangers and side effects. Here are five possible risks associated with the use of ganoderma:

1. Allergic reactions: Some individuals may experience allergic reactions to ganoderma, especially if they have a known allergy to mushrooms or other fungi. Symptoms can range from mild itching and rashes to more severe reactions like difficulty breathing or swelling.

2. Blood thinning effects: Ganoderma has natural blood-thinning properties, which means it may increase the risk of bleeding in some individuals. If you’re already taking anticoagulant medications or have a bleeding disorder, consult your healthcare provider before using ganoderma.

3. Interactions with medications: Ganoderma supplements can potentially interact with certain medications, including immunosuppressants and antiplatelet drugs. This could affect their effectiveness or lead to unwanted side effects.

4. Digestive issues: In some cases, ganoderma consumption has been linked to digestive issues such as upset stomach, diarrhea, or constipation. These symptoms are usually mild and temporary but should be monitored closely.

5. Lowered blood pressure: Ganoderma has been shown to have hypotensive effects on blood pressure levels in some studies. While this can be beneficial for those with high blood pressure, individuals with low blood pressure should exercise caution when using ganoderma.

It’s crucial to remember that individual responses may vary when it comes to herbal remedies like ganoderma. If you experience any unusual symptoms or concerns after starting its use, discontinue immediately and consult a healthcare professional for further guidance.

How to Prepare Ganoderma for Medical Use

Reishi mushrooms can be prepared in various ways for medicinal use, depending on your preferences and the specific health goals you have in mind. Here are some common methods of preparation:

Decoction (Boiled Ganoderma)

  1. Start with dried Ganoderma slices or whole mushrooms.
  2. Add them to a pot of water (typically 3-5 cups of water for every 20-30 grams of dried Ganoderma).
  3. Bring the water to a boil, then reduce the heat to a simmer.
  4. Allow it to simmer for 1-2 hours, or even longer for a stronger decoction.
  5. Strain the liquid and consume the tea. You can re-boil the same Ganoderma pieces for additional batches.

Ganoderma Tea

  • You can use Ganoderma in tea form by steeping Ganoderma slices or powder in hot water for 10-15 minutes. This is a milder preparation compared to a decoction.

Extracts and Supplements (Capsules and Tablets)

  • Ganoderma is also available in supplement forms, such as capsules and tablets. Follow the dosage instructions provided on the product label. These supplements are convenient for people who prefer not to prepare Ganoderma themselves.

Ganoderma Powder

  • Ganoderma is available in powdered form. You can mix this powder with water, juice, or your favorite beverage for easy consumption.


  • Ganoderma tinctures are made by soaking the mushroom in alcohol or glycerin. The resulting liquid can be taken orally, typically in drop form.

Infusions and Herbal Blends

  • You can infuse Ganoderma with other herbs or teas. For example, you can combine it with green tea, ginseng, or other herbs to create a custom herbal blend.

Raw Ganoderma

  • While it’s possible to consume Ganoderma raw, it’s not common due to its tough and woody texture, which can be difficult to digest. Most people prefer to prepare it in a more palatable form, like tea or supplements.

When using Ganoderma for medicinal purposes, it’s essential to pay attention to dosage recommendations, especially when taking supplements. Also, keep in mind that individual responses to Ganoderma may vary, and it’s advisable to consult with a healthcare professional, particularly if you have underlying health conditions or are taking other medications. Additionally, if you’re foraging for wild Ganoderma, make sure you can properly identify it to avoid any toxic species, as not all Ganoderma varieties are suitable for consumption.
