Rating (out of 5): 2

Root tubers, such as those from plants like Dioscorea (yam), Pueraria (kudzu), or Asparagus racemosus (shatavari), have a long-standing history in various traditional medicine systems, including Ayurveda, Traditional Chinese Medicine (TCM), and African herbal practices. In these systems, root tubers are believed to nourish and strengthen the body, including the heart. For example, in Ayurveda, certain root tubers are classified as "rasayana" or rejuvenating herbs, thought to improve vitality and support weak organs, including the heart. Similarly, in TCM, some root tubers are used in formulas intended to "tonify Qi" and "nourish the blood," both of which are considered important for cardiac health and for treating symptoms associated with heart weakness, such as fatigue and palpitations.

However, the evidence for these uses is largely anecdotal and based on traditional knowledge rather than rigorous scientific validation. While some root tubers contain bioactive compounds that may have cardiovascular effects (such as saponins, flavonoids, and polysaccharides), direct evidence from clinical trials supporting their efficacy in treating heart weakness is limited. Therefore, their use for heart weakness is justified mainly by tradition, and while there is some preliminary scientific interest, the strength of evidence remains modest.
