D&C 42:43 teaches “And whosoever among you are sick, and have not faith to be healed [by priesthood blessings], but believe, shall be nourished with all tenderness, with herbs and mild food…”
Mild foods and herbs can help heal the sick in addition to, and in the absence of, reliable medical care.
Doctrine and Covenants 89, commonly known as The Word of Wisdom, helps us understand what, and what not, to eat or consume (and some of it sparingly).
Alma 46:40 helps us understand the value of herbal medicines. “…there were some who died with fevers, which at some seasons of the year were very frequent in the land—but not so much with fevers, because of the excellent qualities of the many plants and roots which God had prepared to remove the cause of diseases, to which men were subject…”
Considering the above scriptures, it would wise to research and understand the healing properties of foods and to research reliable herbal medicines for the treatment of disease and other health issues.
