Turmeric is another herb that has been traditionally used to treat eye styes. Turmeric has powerful natural antibacterial and anti-inflammatory properties that help to combat infection and reduce pain and swelling. The curcumin in turmeric helps boost the immune system, assisting the body to fight off infection and speed healing. To use turmeric, add one tablespoon of turmeric to two cups of water and bring to the boil. Boil until the water has reduced by half, then remove from the heat and cool. Strain the mixture through a piece of clean cheesecloth. Bathe the affected eye with this solution three or four times a day. Repeat until you experience relief.
