Nux Vomica 30C comes into its own during the holiday season! Perhaps you've celebrated a little too hard and have trouble getting going the next morning? Try a couple of doses of Nux Vomica.
Also try nux vomica at the first sign of a cold, when there's very little discharge, only a dry tickling sensation in the nose and frontal sinuses and sneezing, accompanied by a frontal headache. The nose is obstructed at night. Sensitive to drafts. Chilly and irritable. Dilute in a glass of water and take a tablespoon every couple of hours, stirring vigorously each time.
