For those that demand scientific proof to every problem, these home approaches to curing bad breath are unlikely to satisfy you. Still, though scientifically unproven, the anecdotal evidence suggests that there are plenty of things you can do to combat your halitosis problem at home, many of them readily available from your pantry or refrigerator.

Here’s how to get started in reducing your bad breath from home.

Well-known herbs that combat bad breath:

1. Parsley (Petroselinum sativum). Traditionally, parsley has been used to correct so-called “acute” bad breath, especially the odors associated with a meal rife with onions and garlic (which is why parsley so often appears on the plate next to your pasta dish).

Parsley is a terrific natural neutralizer. Its leaves are rich in chlorophyll, a noted anti-mutagen and one of nature’s best deodorizers, especially against the fecal odors associated with some bad breath. Chew on some Parsley leaves for fresh breath and a mineral boost. One thing to take note of: parsley should be eaten fresh, as the dried form isn’t nearly as effective.

2. Sage (Salvia officinalis). Sage is historically used to soothe a sore throat and help reduce gingivitis. Sage works by drying out the excess mucus that forms in a sinus infection, reducing the breeding ground available to hostile bacteria.

3.Thyme (Thymus vulgarus). Thyme is an ancient remedy for bad breath (among many other health issues). Thyme is commonly used to soothe sore throats and to lessen the symptoms of colds and flus. Used as a mouth rinse, thyme acts as a strong natural antiseptic and an effective killer of fungus, bacteria and virus. Brew your own tincture of thyme for best results, and avoid the ornamental varieties, which are less effective.

4. Clove (Eugenia aromaticum). Clove is an excellent remedy for  bad breath caused by putrifying food in mouth. Clove made a frequent appearance in mouthwashes and dentifrices from the old days. However, this herb can be drying.

5. Myrrh (Commiphora molmol). Exotic as it is, Myrrh makes a powerful case against bad breath, as well as gingivitis, sinus infections and cold symptoms found in the mouth and throat. Myrrh has enjoyed a long history in the battle against gum disease and toothaches.

6. Echinacea, Purple Coneflower or Snake root (E. angustifolia, E. purpurea, E. pallida, and E. tennessiensi). In addition to giving the immune system a boost, this herb also increases the amount of saliva in your mouth, and consequently acts as a mouth rinse. Echinacea has also been used for sore throat and gingivitis.

7. Wild Indigo (Baptisia tinctora). Wild Indigo also stimulates the immune system, and effectively treats sore throat, mouth and gum abscess. It also serves as an excellent, non-drying mouthwash.
 
8. Spilanthes, Toothache plant (Spilanthes oleracea). Spilanthes is both antifungal and antibacterial. It’s useful against thrush, pyorrhea, gingivitis and toothache.

9. Frankincense (Boswellia carterii). This second Biblical herb is a useful antibacterial, used topically for sores and toothache. Frankincense also improves circulation.

10. Goldenseal, Oregon Grape and Barberry. All three make excellent topical solutions for mouth rinses and infected sore throats.

11. Lemon juice. Add the juice of one fresh lemon to a little sugar and a pinch of salt. Dilute with water. Sip the mixture slowly throughout the day.

12. Fenugreek (Trigonella foenum-graecum). Brew up some tea made from Fenugreek seeds to help lessen mouth odor.

13. Peppermint (Mentha piperita). Mix three parts fresh peppermint leaves with two parts of water. Grind in blender until solution is thick. Gargle one cup of the solution everyday for one week. Each day your breath should improve. Make fresh concoction every other day, as fresh herbal concoctions can quickly spoil. Store your solution in the refrigerator, tightly sealed.

14. Acidophilus. Take acidophilus supplements, or chew Uemboshi plums to improve the health of your intestines.

15. Guava. Slowly chew a very green Guava fruit to help lessen the intensity of halitosis.

16. Cardamom (Elettaria cardamomum). Chew a green cardamom after and between meals to help improve your breath. Or chew some cardamom seeds. The aromatic flavor in cardamom freshens your breath.
