A common remedy for sore eyes/Conjunctivitis/red eyes in Mangalore is corriander seeds soaked in water.
If you have sore eyes (red corneas often accompanied with sticky discharge which quite possibly crusts the eyes closed in the morning) this is a Manglorean home remedy.
Get a teaspoon of coriander seeds, wash them clean of any surface dirt. Tie them up in the corner of a clean handkerchief or muslin cloth. Soak the corner of the cloth with the seeds in about 100 ml of clean water (boiled and cooled or bottled water) for 4-8 hours.
Drop a few drops of the liquid into the affected eyes, 3-4 times daily (or more often if there is a lot of oozing). Make a fresh liquid at least every 24 hours.
The liquid from the coriander seeds is also cooling and soothing for tired eyes.
