The medical benefits of tea have always been well-known.
The Emperor Shen Nong, the father of Chinese agriculture and medicine once remarked: "Tea relieves tiredness and strengthens the will, warms the soul and revives eyesight." Conventional medicine then discovered the reasons behind the magical properties of tea.
All teas contain caffeine (or theine). However, the caffeine present in tea is different from that found in coffee. It stimulates the nervous system in a slow and progressive way. It helps you to feel awake and concentrated in a sustainable way.
Tea contains tannins and polyphenols, these are rich in antioxidants. The polyphenols present in green tea are excellent for combating high cholesterol and for the prevention of cardiovascular diseases.
Tea is also rich in vitamins, notably vitamin P (to help strengthen hair) and vitamin B (especially vitamin B9) which helps to maintain general wellbeing. Tea also contains fluoride, which is good for maintaining teeth enamel.
Rooibos, a caffeine free drink, is also rich in polyphenols which have antioxidant and relaxing qualities.
It is therefore best drunk in the late afternoon and evening.
