What You'll Learn
Reishi mushrooms may cause digestive issues and skin rashes
Reishi mushrooms are generally considered safe, but they may cause digestive issues and skin rashes in some people. While reishi mushrooms have been used for thousands of years with very few side effects recorded, occasional mild digestive upset and skin rashes may occur in sensitive individuals with impaired immune systems. These side effects appear to be temporary and are not considered dangerous. However, it is important to note that there is limited research on the long-term effects of reishi mushroom consumption.
Digestive issues associated with reishi mushrooms may include nausea, dry mouth, and upset stomach. These symptoms typically resolve on their own and do not require medical intervention. However, it is always recommended to consult a healthcare professional if any adverse reactions occur. In addition, reishi mushrooms may interact with certain medications, such as blood thinners and immunosuppressants, and may increase the risk of bleeding in individuals with bleeding disorders or those undergoing surgery.
The potential for liver toxicity associated with reishi mushroom consumption has been noted. While research from 2004 found no detrimental effects on the liver or kidneys in healthy adults who took reishi mushroom extract for four weeks, other case studies have reported significant liver problems. However, it is challenging to determine if the mushroom itself was solely responsible for the observed liver damage due to other factors involved. Individuals with liver conditions or those taking medications that affect the liver may want to exercise caution when considering reishi mushroom supplementation.
Skin rashes are another possible side effect of reishi mushroom consumption. These rashes are typically mild and may be associated with itching or dryness. As with any allergic reaction, discontinuing the use of reishi mushrooms and consulting a doctor is advised if a rash occurs. While reishi mushrooms are not known to cause severe allergic reactions, it is always better to be cautious when it comes to your health and well-being.
Overall, while reishi mushrooms offer potential health benefits, it is important to be aware of possible side effects, including digestive issues and skin rashes. Individuals considering reishi mushroom supplementation should consult a healthcare professional to ensure safe and appropriate use, especially if they have any pre-existing health conditions or are taking medications.

They may be unsafe for pregnant or breastfeeding women
Reishi mushrooms are generally considered safe and well-tolerated by most people. However, there may be certain instances where caution is necessary, especially for pregnant or breastfeeding women.
Firstly, it is important to note that there is limited research on the safety of reishi mushrooms for pregnant or breastfeeding women. As a result, the potential risks and side effects for these individuals are not yet fully understood. Therefore, it is generally recommended that pregnant or breastfeeding women avoid consuming reishi mushrooms unless under medical supervision.
Reishi mushrooms have been associated with an increased risk of bleeding, especially in people with certain bleeding disorders or those taking blood-thinning medications. Pregnant or breastfeeding women may have unique considerations regarding blood clotting and need to be cautious. Additionally, reishi mushrooms can interact with blood pressure medications, which may be another concern for pregnant or breastfeeding women as blood pressure regulation can be crucial during these periods.
Furthermore, reishi mushrooms can cause digestive side effects, although these are typically mild and occur in sensitive individuals with impaired immune systems. Nevertheless, pregnant or breastfeeding women may experience changes in their digestive systems, and the potential impact of reishi mushrooms in this context warrants consideration.
While the benefits of reishi mushrooms are often highlighted, it is important to approach their consumption with caution, especially for pregnant or breastfeeding women. The lack of sufficient research in these specific populations means that potential side effects are not yet fully understood. Therefore, it is advisable to consult with a healthcare professional before consuming reishi mushrooms during pregnancy or while breastfeeding to ensure the best possible care and guidance for individual circumstances.

They could increase the risk of bleeding
Reishi mushrooms are thought to have several health benefits, but they can also cause side effects and may be unsafe for certain people. One of the purported effects of reishi mushrooms is their ability to regulate the immune system. However, despite their popularity, some have questioned their safety.
Reishi mushrooms may increase the risk of bleeding in certain individuals. In particular, people with bleeding disorders or low platelet counts should exercise caution when consuming reishi mushrooms, as higher doses may increase the likelihood of bleeding. Additionally, those taking blood pressure medications, blood thinners, chemotherapy drugs, or immunosuppressant medications should refrain from consuming reishi mushrooms due to their potential impact on blood clotting.
The risk of bleeding may be heightened for individuals taking other herbs or supplements that affect blood clotting, such as Ginkgo and fish oil. It is crucial to consult a doctor before consuming reishi mushrooms, especially for those with medical conditions or taking medications, to ensure safe usage and avoid potential interactions or side effects.
While reishi mushrooms are generally well-tolerated by most people, some mild digestive issues and skin rashes may occur, particularly in individuals with impaired immune systems. It is important to note that the side effects of reishi mushrooms can become more likely or severe when consuming excessive amounts. Therefore, it is advisable to carefully follow the recommended directions and dosage instructions to minimise potential adverse effects.

They may interfere with blood pressure medications
Reishi mushrooms are believed to have a wide range of health benefits, including reducing fatigue, improving cholesterol, and boosting the immune system. They are available over the counter as herbal supplements in the form of tablets, capsules, extracts, powders, and teas. However, it is important to be aware of potential side effects and risks associated with consuming reishi mushrooms, especially for individuals taking blood pressure medications.
Reishi mushrooms have been shown to lower blood pressure and slow blood clotting. Taking reishi mushrooms along with medications that also lower blood pressure or slow blood clotting may cause additive effects, resulting in a significant drop in blood pressure and an increased risk of bruising and bleeding. Therefore, individuals taking blood pressure-lowering medications should exercise caution when considering consuming reishi mushrooms. It is advisable to consult a doctor or healthcare professional before taking reishi mushrooms to ensure they will not interfere with any current medications or health conditions.
Additionally, reishi mushrooms may interact with other supplements or herbs that affect blood clotting or blood pressure. For example, combining reishi mushrooms with supplements such as ginkgo or fish oil, which can impact blood clotting, may enhance the risk of bleeding or bruising. It is crucial to inform your doctor about any supplements or herbs you are taking to allow them to assess potential side effects or interactions.
The consumption of reishi mushrooms is generally considered safe for most people when used appropriately. However, it is always recommended to consult a healthcare professional before adding any new supplement to your routine, especially if you have existing health conditions or are taking medications, to ensure the safe and effective use of reishi mushrooms.

They may cause liver damage
Reishi mushrooms are generally considered safe and well-tolerated by most people. However, as with any supplement, there are potential side effects to be aware of. One concern is that reishi mushrooms may cause liver damage, especially when consumed in powdered form for longer than one month. This is a serious adverse effect, and liver toxicity can even lead to death.
It is important to note that research on the side effects of reishi mushrooms is limited, and the existing studies have produced mixed results.

However, due to the potential risk of liver damage, it is recommended to consult a doctor before consuming reishi mushrooms, especially for those with existing liver conditions or other health concerns.
Additionally, reishi mushrooms may interact with certain medications, including blood pressure medications and blood thinners. They can also increase the risk of bleeding, especially in people with low platelet counts or bleeding disorders. As a result, it is crucial to inform your doctor about any supplements you are taking, even if they are natural, to ensure they do not interfere with your medications or health conditions.
Pregnant and breastfeeding women should also exercise caution as there is limited research on the safety of reishi mushrooms during these periods. While some sources recommend avoiding reishi mushrooms altogether during pregnancy and breastfeeding, others suggest consulting a doctor for medical supervision. Overall, it is essential to be cautious and informed when considering the use of reishi mushrooms, especially given the potential risk of liver damage and other side effects.
