What are the homeopathic remedies for chalazions?

Warm compresses: A "stye, " a.K.A. Hordeolum, is a plugged oil gland in the eyelid, sort of like a pimple. Most of the time, it can be effectively treated with warm compresses. These loosen the oils and allow them to be expressed from the lid. If persistent, a hordeolum can become a chalazion, which often needs either a steroid injection or surgical excision. See an ophthalmologist to be sure.

Warm compresses may help too! for styes that are very painful and hypersensitive to touch or cold, hepar sulphuris may work.
