You can grow a years' supply of garlic for a family of five in a few weeks. It really doesn't have to cost anything at all. So, before we get involved in using either chemical drug or herbs or anything else to accelerate or decelerate functions of the body, we should attempt to do it by judicious diet along the nutritional line. People do not a good understanding of how to eat correctly, or what to eat. There are just so many contradictory notions about what micronutrient causes or prevents what disease.
Nobody can make sense of it at all.
Humans have lived their lives for tens of thousands of years, without food pills, and without medicating themselves before and after every meal. Food is your best medicine. The only people who doubt this, or believe it is false, are those who have no understanding of human food and sustenance, or those who have a vested interest in profiting from people buying their unnecessary products. Health is a really combination of factors, besides just not suffering immediate symptoms. True health also involves one's peace of mind, happy and harmonious relations with relations, having friends, and satisfying work that makes a meaningful contribution to the world.
