A passage from a once popular song by Simon and Garfunkel “..parsley sage, rosemary, and thyme.. Remember me..” tells us about memory herbs ;-)
In Thailand บัวบก พรมมิ กลีบบัวแดง ขมิ้น (Turmeric) are said to help memory function when regularly eaten.
But good food (of all 5 groups of food) are the basic of good health,good brain and good memory.
