Dr. Christopher’s Nerve Formula comes in two different forms:
Ear & Nerve extract (alcohol base) is made to be used both orally (in mouth) and directly in the ears.
Nerve Formula (glycerine base) extract is NOT to be used in the ears. I prefer this glycerine base extract for oral use, since it tastes better than the Ear & Nerve Formula.
The ingredients of each option is viewable after you chose the form & size you desire in the dropdown menu.
