Reishi cannot eliminate nodules. Ganoderma lucidum is the dried fruiting body of the fungus Ganoderma lucidum of the family Polyporaceae, the red or purple ganoderma lucidum, which is sweet in flavor and flat in nature, and belongs to the heart, lung, liver and kidney meridians, and has the effects of tonifying qi and tranquilizing the mind and relieving coughs and wheezing (stopping coughs and calming wheezing), but has no efficacy in dispersing knots, and therefore cannot eliminate nodules. Lingzhi is clinically used for the treatment of restlessness, insomnia and forgetfulness, body fatigue and fatigue of the spirit (dysphoria), coughing and wheezing with lung deficiency, and inability to think about food and drink. The adverse reactions and contraindications of Ganoderma lucidum are not clear at the moment. Patients with nodules should not blindly treat with Ganoderma lucidum to avoid delaying the condition. If you need to use Lingzhi, it is recommended to go to the hospital and use it under the guidance of a professional physician to identify the symptoms.
