Based on clinical pharmacology reports

Mechanisms involved in interactions are liver enzymes. Reishi interacts with cytochrome P450, potentially altering drug metabolism. It can also affect platelet activity and insulin sensitivity. These biological mechanisms can create unpredictable responses when used with pharmaceutical products. So caution should be observed.

Implement safety protocols before considering reishi. Complete a thorough list of supplements. Discuss timing with pharmacist; staggered dosing may reduce risks. Never self-prescribe reishi while taking prescriptions without professional assistance in monitoring your bodily responses closely.
