"If you want to live well, then you must eat wisely. But eating wisely [with modern methods] may not prevent you from becoming sick."

"Something is missing from grocery-bought or common foods. Yet, if these inadequate or 'weak' foods can support life, then 'strong' foods must be able to strengthen and protect life. This kind of reasoning has driven Taoists to investigate the jungles, mountains, flatlands and bodies of water -- and to test every plant, animal and mineral -- for properties that will benefit mankind. Their findings produced other dietary wisdom teachings that became the right arm of Taoist practice.

"Taoism exists because of herbs. All Taoists depend on herbs, just as we depend on food."
