Panax ginseng has a long history of use in traditional medicine, particularly in East Asian cultures, for supporting recovery during convalescence—the period of gradual recovery after illness or medical treatment. In traditional Chinese medicine (TCM), ginseng is valued as a "qi" (energy) tonic, reputed to restore strength, vitality, and resilience in individuals weakened by disease or stress. Historical texts and centuries of anecdotal usage cite ginseng's purported abilities to enhance energy, support immune function, and improve general well-being, making it a common component in convalescent care formulas.

Scientific research has begun to investigate these traditional claims, but direct evidence supporting ginseng’s efficacy specifically for convalescence remains limited. Some studies suggest that Panax ginseng may help reduce fatigue, improve physical performance, and modulate immune function in certain populations. However, these studies often focus on healthy individuals, the elderly, or those with chronic fatigue, rather than patients in a defined state of convalescence. Systematic reviews generally conclude that while ginseng may confer mild benefits in terms of energy and immune support, robust clinical evidence for its routine use in convalescence is lacking.

In summary, the use of Panax ginseng for convalescence is primarily justified by tradition, with moderate supporting evidence from historical and ethnobotanical sources, but only limited and indirect scientific validation to date.
