Sage has been used in ancient Chinese medicine to protect against age related memory loss by increasing blood flow to the cortex. Sages, especially those who live in the mountains where the air is thinner, use this to keep their memory and brain functioning sharply.
Sage is very good at fighting off inflammation, which is why it’s a good treatment for rheumatoid arthritis and asthma.
It can help treat nausea and upset stomach and it’s easy on digestion as well. It tastes great in many warm foods like soup. Take about 1 teaspoon per day. If you grow it in your garden it does not need much water.
