Take a look at the Chinese people, wherever they go they carry a thermos flask, whether it’s hot water infused with tea, red dates, goji berry, roses or hawthorn or the worst just hot water.

All organisms in nature have to abide by this rule. Also, what to supplement differs from person to person. For example, people with stomach problems shouldn't eat a lot of solid foods like meat. They should eat things like lotus porridge, yam porridge, porridge with slices of fish meat; things that are easy to digest. People with lung problems? They should use lily buds and wolfberries when they make tea.
