Please describe to me home remedies for a dry cough?

None specific: If your cough is of few days and not more than a week and w/o fever, you can increase water intake; do saline gargles at night or 2x/day; increase your vitc intake with fruits or tablets, hopefully helps. If your cough is w/ fever, you need to see an md to r/o bacterial infection. If you're asthmatic with cough, see md asap. For cough >than 2 weeks, you need a doctor's evalauation.
