AMLA: THE AYURVEDIC WONDER
Medicinal plants have been used for centuries to promote a disease-free healthy life. Phyllanthus emblica Linn. (also known as Indian gooseberry or amla) is an important medicinal plant used in traditional health care systems like Ayurveda and Unani. The plant is highly nutritious and contains various compounds like phenolic compounds, tannins, and vitamins, making it an important source of dietary supplements. Several parts of the plant have been used to treat various ailments, including diarrhea, jaundice, and inflammation. Additionally, the plant exhibits antidiabetic, hypolipidemic (4), antibacterial, antioxidant, and hepatoprotective properties (1). Numerous phytochemicals have been isolated from the plant, and its ethnomedical and pharmacological potentials have been extensively studied (2). Further research is required to identify and evaluate the chemical constituents for nutritional and therapeutic potential. In a randomized, double-blinded, placebo-controlled study, ingestion of lingonberry and amla fruit extract (LAE) showed significant improvements in skin elasticity, thickness, stratum corneum water content, and degree of wrinkles, indicating that LAE may be considered a candidate anti-aging agent for preventing skin weakening (3).

VITAMIN C DEFICIENCY IN INDIAN POPULATION
A population-based cross sectional survey in two areas of north and south India were investigated for the prevalence of vitamin C deficiency in people aged more than 60. The age, sex and season standardized prevalence of vitamin C deficiency was 73.9% in 2668 people in north India and 45.7% in 2970 from south India (1). This indicated the poor nutrition and lower dietary intakes of vitamin C in communities of Indian population.
A cross-sectional study on adults from Western India was done to examine interrelationships between (a) dietary habits, (b) socioeconomic and (c) environmental factors, and their impact on plasma ascorbic acid (2-3). Subnormal status of vitamin C was observed and the study emphasizes the need to increase consumption of fruit, Green leafy vegetables and milk products, and also better education and environment.

SUPPORTS IMMUNITY
Scientific evidence suggests that vitamin C supplementation in adults and children with a common cold can significantly reduce its duration and severity and relieve cold symptoms (1-2). Furthermore, supplementation with vitamin C appears to be able to both prevent and treat respiratory and systemic infections.
Three controlled trials found that vitamin C prevented pneumonia (3). Two controlled trials found a treatment benefit of vitamin C for pneumonia patients.
