A mouthwash combination that includes sage oil, peppermint oil, menthol, chamomile tincture, expressed juice from echinacea, myrrh tincture, clove oil, and caraway oil has been used successfully to treat gingivitis.⁷ In cases of acute gum inflammation, 0.5 ml of the herbal mixture in half a glass of water three times daily is recommended by some herbalists. This herbal preparation should be swished slowly in the mouth before spitting out. To prevent recurrences, slightly less of the mixture can be used less frequently.

A toothpaste containing sage oil, peppermint oil, chamomile tincture, expressed juice from Echinacea purpurea, myrrh tincture, and rhatany tincture has been used to accompany this mouthwash in managing gingivitis.⁸

Of the many herbs listed above, chamomile, echinacea, and myrrh should be priorities. These three herbs can provide anti-inflammatory and antimicrobial actions critical to successfully treating gingivitis.

The potent effects of some commercial mouthwashes may be due to the inclusion of thymol (from thyme) and eukalyptol (from eucalyptus)—volatile oils that have proven activity against bacteria. One report showed bacterial counts plummet in as little as 30 seconds following a mouthrinse with the commercial mouthwash Listerine™, which contains thymol and eukalyptol.⁹ Thymol alone has been shown in research to inhibit the growth of bacteria found in the mouth.^10,11 Because of their antibacterial properties, other volatile oils made from tea tree,¹² clove, caraway, peppermint, and sage,¹³ as well as the herbs myrrh¹⁴ and bloodroot,¹⁵ might be considered in a mouthwash or toothpaste. Due to potential allergic reactions and potential side effects if some of these oils are swallowed, it is best to consult with a qualified healthcare professional before pursuing self-treatment with volatile oils that are not in approved over-the-counter products for halitosis.

Carminatives (also called aromatic digestive tonics or aromatic bitters) may be used to relieve symptoms of indigestion, particularly when there is excessive gas. It is believed that carminative agents work, at least in part, by relieving spasms in the intestinal tract.¹⁶

Among the most notable and well-studied carminatives are peppermint, fennel, and caraway. Double-blind trials have shown that combinations of peppermint and caraway oil and a combination of peppermint, fennel, caraway, and wormwood have been found to reduce gas and cramping in people with indigestion.^17,18,19 Generally, 3–5 drops of natural essential oils or 3–5 ml of tincture of any of these herbs, taken in water two to three times per day before meals, can be helpful. Alternately, a tea can be made by grinding 2–3 teaspoons of the seeds of fennel or caraway or the leaves of peppermint, and then simmering them in a cup of water (covered) for ten minutes. Drink three or more cups per day just after meals.

Caraway relieves intestinal cramping and, in this way, may ease symptoms of colic. One tablespoon (15 grams) of caraway seed is mixed with 8 oz (240 ml) of just-boiled water and steeped in a closed container for at least 10 minutes. Three ounces of vegetable glycerin is added, and the resulting mixture is stored in a bottle in the refrigerator. Up to 1/2 teaspoon (2.5 ml) of the liquid may be given every 30 minutes to a colicky infant or given 15 minutes before feeding.²⁰
