A sty (hordeolum) is a red, painful lump near the edge of your eyelid that may look like a boil or a pimple which is often filled with pus. Other than this, eyelid pain, eyelid swelling, tearing and crusting around the eyelids are also some of the manifestations.
Sty is caused by an infection brought about by staphylococcus bacteria. Sty is classified as either external or internal.
An external sty (on the outside of your eyelid) may be caused by an infection of an eyelash follicle (a structure where individual eyelash grows), an infection of the sebaceous (Zeis) gland (gland attached to the eyelash follicle and produces an oily substance called sebum, which lubricates the eyelash to prevent it drying out) and an infection of the apocrine (Moll) gland (a sweat gland that empties into the eyelash follicle; the fluid joins the tear film that covers your eye and prevents the eye from drying out).
On the other hand, an internal sty is caused by an infection of the meibomian gland which are found on the eyelids and produce an oily liquid, which makes up part of the tear film that covers your eye.
Since sty is most commonly due to bacterial infection, its treatment will focus on eliminating the etiologic agent. However, it is also necessary to manage other symptoms associated with sty in order to remove the discomfort. One of the most common home remedy for sty is tea bag. Tea is known for its antibacterial elements known as tannin. Hence, it would help in relieving inflammations, swelling and pain. To ensure effectiveness, wet tea bags should be applied on the eyelids for a few minutes.
Aside from this, chamomile herb can also help relieve swelling and redness of the infected area with its anti-inflammatory effect. To use this as a remedy, one teaspoon of dried chamomile should be soaked in hot water for 15 minutes. Strain and apply the chamomile water using a clean cloth.
