Green Tea

Green Tea
The plant Camellia sinensis yields three types of tea based on the level of fermentation: green, white and black. Green Tea (unfermented) is steamed to stop oxidation by air and is considered to have more health benefits than black and white tea.
Green Tea is a good beverage for weight loss and weight maintenance as it is a low calorie drink. It is rich in catechins that increase metabolism and fat breakdown and inhibit lipid absorption. Thus, it can easily be adopted as a morning beverage or can be consumed before and after meals to accelerate the process of weight loss. Consumption of 2 to 4 cups of Green Tea is sufficient for weight loss and other health benefits.
Additionally, Green Tea also improves skin health. It aids in better blood circulation and reduces premature ageing due to its antioxidant nature. Topical application of Green Tea polyphenol- formulated skin care products can be beneficial in achieving soft, supple and young looking skin. Green Tea can also be beneficial for preventing hair loss, dandruff, baldness and psoriasis due to its anti-inflammatory and stress-inhibitory properties.
According to Ayurveda, Green Tea has Deepan (appetizer) and Pachan (digestive) properties that help improve the digestive system and aid in weight loss. Due to its Kshaya (astringent) properties, it helps in maintaining the elasticity and firmness of the skin.
Though Green Tea is safe to consume, excessive consumption may cause nausea, dizziness, heartburn, irregular heartbeat or other side effects associated with high caffeine content[1][49][50-53].
