Treat disease through diet, by preference, refraining from the use of drugs; and if you find what is required in a single herb, do not resort to a compound medicament....

Abstain from drugs when the health is good, but administer them when necessary .-- Tablet to a Physician In one of His Tablets 'Abdu'l-Baha says:-- O seeker after truth! There are two ways of healing sickness, material means and spiritual means.

The first way is through the use of material remedies.

The second consists in praying to God and in turning to Him.

Both means should be used and practiced....
Moreover, they are not incompatible, and you should accept the physical remedies as coming from the mercy and favor of God Who has revealed and made manifest medical knowledge, so that His servants may profit by this kind of treatment also.
He teaches that, were our natural tastes and instincts not vitiated by foolish and unnatural modes of living, they would become reliable guides in the choice both of appropriate diet and of medicinal fruits, herbs and other remedies, as is the case with wild animals.
