If anyone is looking for a good read i recomend prescription for nutritional healing 5th addition.
I bought it about a year ago and just finished up today.
Its around 830 pages of natural ways to treat/cure problems such as poor apetite, hbp, Aging, Acne, Muscle pains/Aches, sexual disfunction & many other problems.
It also has a A-Z guide on vitamins & minerals even a good description on majority of the amino acids.
Definetly give it a thumbs up!
