Can cortisone 10 be used for ringworm?
RINGWORM is in fact not a parasite, but a fungi. The scientific term for Ringworm is "Tinea" which means "growing worm". (thus here is the origin of the worm part of ringworm, ring is obviously the shape in which the fungi grows, in a circle) It is a common mistake to think that ringworm is a parasite. but it is in fact a fungi.
That depends the reason why the cortisone was indicated. If it was for skin disorders, there are some herbal extracts with effects that may mimic cortisone effects: Astragalus Root, Vitex Fruit. In homeopathy you may use Cortisone Aceticum in potency CH30. You should consult a trained holistic veterinarian for the right use of the remedies referred above, see the link below
