Taking chaga and reishi together may significantly increase the risk of bruising or bleeding. Both mushrooms have 'blood-thinning' properties, meaning they can slow down how quickly your blood clots. Combining them can have an additive effect, making it harder for your body to stop bleeding if you are injured. Additionally, both may lower blood sugar levels, which could lead to symptoms of low blood sugar (hypoglycaemia) such as dizziness or shakiness.

Why this happens
Both chaga and reishi contain compounds that interfere with platelet aggregation (the way blood cells stick together to form clots). Chaga is also high in oxalates which can affect metabolism. Furthermore, both fungi possess hypoglycaemic properties, meaning they can both lower blood glucose through similar pathways in the body.
What you should do
Use caution when combining these supplements. If you are scheduled for surgery, stop taking both at least two weeks beforehand. You should consult your doctor before taking this combination if you are already taking prescribed blood thinners (like warfarin or aspirin), blood pressure medication, or diabetes medication. Monitor yourself for signs of unusual bruising, nosebleeds, or light-headedness.

Can I take Amlopadine and Atorvastatin together?
Taking amlodipine and atorvastatin together can increase the amount of atorvastatin in your blood. This may increase the risk of side effects, particularly muscle pain, tenderness, or weakness (a condition called myopathy). In rare cases, this can lead to a more serious muscle breakdown called rhabdomyolysis.
