Homeopathically, there are a number of acute remedies designed to treat conjunctivitis. These include Pulsatilla (windflower, Pulsatilla nigricans), Belladonna, and eyebright (Euphrasia officinalis). Eye drops, prepared with homeopathic remedies and/or herbs, can be a good substitute for pharmaceutical eye drops. Eye washes can also be made. Herbal eyewashes made with eyebright (1 tsp. dried herb steeped in 1 pint of boiling water) or chamomile (Matricaria recutita; 2-3 tsp. in 1 pint of boiling water) may be helpful. Eyewashes should be strained and cooled before use, and close attention should be paid to make sure that any solution put into the eye is sterile. Other simple home remedies may help relieve the discomfort associated with conjunctivitis. A boric acid eyewash can be used to clean and soothe the eyes. A warm compress applied to the eyes for five to 10 minutes three times a day can help relieve the discomfort of bacterial and viral conjunctivitis. A cool compress or cool, damp tea bags placed on the eyes can ease the discomfort of allergic conjunctivitis. http://www.healthatoz.com/healthatoz/Atoz/ency/conjunctivitis.jsp
