This is an ultimate solution for all—young and old. Before going to bed, just rub vicks vaporub on your feet, massage properly, wear socks and have a good night sleep. The next morning, you are absolutely relieved of cough. Trust me. I have tried that with my kids.
Chew saunf or ani seeds time to time. You can also chew a few leaves of Tulsi plant or Gurgle with camphor water on a regular basis. You can also chew cardamom to fight bad breath. At times for long lasting fresh breath, you can also drink spice tea. Mix 4 whole cloves and 2 tablespoons broken cinnamon sticks in 2 cups of water and let it boil and then strain and drink Mint leaves in hot water also helps in removing bad breath.
To get relief from acidity, chew a clove for sometime or eat a pie of gur or jaggery after meal.
