Echinacea

• Consider taking echinacea, an herb known for the boost it can provide to the immune system. In addition, echinacea kills certain respiratory viruses. These properties make it a natural for treating a sinus infection. You can take echinacea in capsule form or as a tea; it is available in natural-products stores. If you are allergic to ragweed, avoid echinacea.
  
  

Ginger

• Try ginger, a natural pain reliever available in capsules and teas. It is an effective anti-inflammatory, and can prevent or help soothe headaches. Grate fresh ginger into tea.
  
  

Eucalyptus

• Turn to eucalyptus, a natural soother of sore throats, to help to shrink swollen tissues. You'll find eucalyptus lozenges at an herbal store and even at some pharmacies. Or make a pot of eucalyptus tea and breathe in the steam before drinking it.
  
  

Peppermint

• Try peppermint for its anti-inflammatory properties. This herb relieves swollen mucous membranes. Peppermint tea is a soothing beverage; inhale the steam for further relief.
