Reishi mushroom (Ganoderma lucidum), also known as Lingzhi, has been used in Traditional Chinese Medicine (TCM) for centuries as a tonic to support longevity, vitality, and overall health. In TCM, reishi is sometimes recommended for individuals with symptoms associated with "heart weakness," such as palpitations, insomnia, and fatigue, which are often interpreted as imbalances in the heart or spirit ("shen"). Classical texts describe its use for calming the mind, strengthening the heart, and promoting restful sleep, reflecting its role in addressing both psychological and physiological aspects of heart health from a traditional perspective.

From a scientific standpoint, there is limited direct evidence supporting reishi mushroom's efficacy for treating or supporting heart weakness in the Western medical sense (e.g., heart failure or cardiac muscle weakness). Some preclinical and small clinical studies suggest that reishi may have beneficial effects on cardiovascular risk factors, such as lowering blood pressure, reducing cholesterol, and exerting antioxidant effects. However, robust clinical trials specifically investigating reishi for "heart weakness" are lacking, and the existing studies often have methodological limitations or investigate broader cardiovascular health rather than direct cardiac function.

In summary, while reishi mushroom's use for heart support is well-rooted in traditional practices, scientific evidence remains preliminary and indirect. Therefore, its justification is primarily traditional, with modest support from early-stage research.
