C. asiatica (L.) Urban is a medicinal plant widely used in traditional Asian medicine with potential geroprotective properties. Its major bioactive compounds—including asiaticoside, madecassoside, asiatic acid, and madecassic acid—exhibit antioxidant, anti-inflammatory, regenerative, neuroprotective, and cytoprotective activities. Experimental studies demonstrate modulation of signaling pathways involved in oxidative stress, inflammation, apoptosis, extracellular matrix remodeling, and cellular survival, including NF-κB, PI3K/Akt/mTOR, MAPK, Nrf2/HO-1, and TGF-β/Smad pathways. Preclinical evidence further indicates attenuation of cellular senescence, improvement of mitochondrial function, enhanced collagen synthesis, and regulation of cytokine production. In experimental models, C. asiatica has shown beneficial effects on wound healing, skin aging, neuroinflammation, β-amyloid aggregation, neuroplasticity, metabolic dysfunction, and vascular protection. Preliminary preclinical findings also suggest possible effects on telomerase activity and telomere maintenance. However, clinical translation remains limited due to insufficient randomized controlled trials, low oral bioavailability of triterpenoids, variability in extract standardization, and limited pharmacokinetic and long-term safety data. This narrative review summarizes the phytochemistry, molecular mechanisms, pharmacological activities, and potential geroprotective applications of c. asiatica, highlighting its translational relevance in healthy aging and age-related disorders while emphasizing the need for standardized clinical studies.
