Strengthening body's resistance/vital energy

Strengthening body's resistance/vital energy is a therapeutic concept primarily rooted in Traditional Chinese Medicine (TCM), where it is known as Fuzheng therapy (PMID: 28413514). It does not represent a single molecular target such as a receptor or enzyme, but rather describes a multi-faceted physiological state of enhanced host defense and homeostasis (NIH/NCCIH). The biological basis for this effect involves the modulation of the immune system, the endocrine system, and the body's response to oxidative stress (PMID: 30636967). In a clinical context, this approach is often used as supportive care in oncology to mitigate the side effects of chemotherapy or to improve the quality of life in patients with chronic illnesses (PMID: 25535474). Modern pharmacological research identifies substances that produce this effect as adaptogens or immunomodulators, which act on various pathways including the HPA axis and cytokine signaling. Because it encompasses a wide range of biological pathways and systemic responses, it is classified as a therapeutic strategy or pharmacological effect rather than a discrete drug target. Consequently, drug discovery efforts in this area focus on identifying specific molecules within these pathways that can be targeted to achieve the overall goal of increased resilience.
