These combinations of herbs will help fighting off your cold:

• 4 parts dried lavendar
• 4 parts dried rosemary
• 4 parts chopped fresh ginger root or 2 parts ginger powder
• 2 parts dried eucalyptus

Use 1/2 cup of dried herbs or one to two cups of fresh herbs. Crush the herbs first to release their essential oils. Mix the herbs and tie them into a square of muslin or a handerchief. Hang the bag under the faucet as you fill the tub.
The bag can be used to scrub your skin as well.
