摘要

The aging process is essentially a result of a network of biological events including oxidative stress, chronic inflammation, cellular senescence, mitochondrial dysfunction, and neurodegeneration. In the search for effective multi-target anti-aging strategies, there is a growing trend towards the use of plant compounds with strong bioactivities. Among numerous medicinal plants, Urtica dioica and Centella asiatica are two of the most extensively studied for their antioxidant, anti-inflammatory, neuroprotective, and skin-regenerative effects. This paper is a comprehensive review of the phytochemical contents, pharmacological effects, and combined potentials of these plants in the alleviation of aging-related biological markers. Urtica dioica is a plant that is packed with flavonoids, phenolic acids, sterols, and vitamins and it has a strong capability to scavenge free radicals. It also changes the inflammatory pathways and keeps cells alive. Centella asiatica, which is known to have triterpenoids like asiaticoside, madecassoside, and asiatic acid, not only facilitates collagen production but also improves brain function and is effective in getting rid of oxidative and inflammatory stressors that lead to aging. As a result, the duo of these natural products exhibits the most similar functions that can navigate the senescence-associated pathways, attack neuronal loss and preserve skin morphology and physiology. Although there is sufficient preclinical evidence and some clinical trials to support the fact that these two plant extracts have therapeutic effects, the problems related to standardization, bioavailability, safety, and regulatory approval of combined herbal formulations remain. This review bridges the gap between the present mechanistic understanding, clinical utilization, drawbacks, and future directions, thereby, reflecting the potential of U. dioica and C. asiatica as two synergistic anti-aging agents in nutraceutical, cosmeceutical, and integrative medicine frameworks.
