A great water infusion for helping stimulate healing from cuts and bruises. It can be used also internally for stomach and duodenal ulcers, where it will have the same effect.
Comfrey is also demulcent, producing a mucilage that coats and soothes irritated tissues. It will help reduce inflammation, and at the same time lessen scarring.
Comfrey also has expectorant properties and has a relaxing effect on the respiratory membranes. Since it helps relax and soothe membranes, it is useful in coughs, asthma, and bronchitis. As an astringent, comfrey can also help control slow bleeding, as in the case of ulcers.
