Polygonatum, commonly known as Solomon's Seal, is a genus of plants used in traditional medicine systems, particularly in Traditional Chinese Medicine (TCM), where species such as Polygonatum sibiricum (huang jing) are prized for their tonic properties. In TCM, Polygonatum is considered to nourish yin, moisten dryness, and tonify the spleen and lungs. It is sometimes used in formulas intended to address symptoms that could be interpreted as "heart weakness"—such as palpitations, fatigue, or general debility—though it is not specifically classified as a primary heart tonic. Rather, its traditional role is broader, supporting overall vitality and addressing conditions of deficiency that may include cardiovascular symptoms. There is little direct scientific evidence supporting the use of Polygonatum for heart weakness or cardiovascular disease. Most available studies focus on its adaptogenic, anti-fatigue, and anti-diabetic properties, with some animal studies indicating potential benefits for blood glucose regulation and antioxidant activity. However, clinical trials in humans examining cardiac function or specific cardiovascular outcomes are lacking. Thus, while Polygonatum's use for "heart weakness" is rooted in tradition, particularly in TCM, this use is not substantiated by robust scientific research.
