Most disease of the body is caused by poor nutrition. Natural medicine is in natural foods. Most vitamins, supplements, minerals (not all, most) are not able too be utilized by the body because they are unrecognizeable to it as a food. Most folks are somewhat nutrition conscious. They buy "quality" foods, and prepare "square" meals for their families. I say most, I mean that I would hope most in this forum, anyway. BUT, food purchased from the supermarket already has everything going against it. Raised with chemical nutrient, picked prematurely, shipped or stored for too long. (Plant based foods are best eaten within one half hour of harvest. Again, I say BEST, not only.)
Why do I write all this to one who has asked about natural medicines ?
Because healing starts with natural foods. What you can raise in organic, chemical-free soil or what you can find in unspoiled timber, this is what we should all be eating. That said, garlic is a gift with many benefits, as is vinegar, honey, fermented fruit juices, the weeds in your garden, etc.
This is too broad a subject to address exhaustively in one writing. Suffice it to say, we do raise or forage 95% of our food. We are healthy. We have had five children at home, buried one, and still carry on in pursuit of independance.
There is the matter of faith and commitment in what we choose to do, but that is another story. There is no "try". It is do, or do not do.
