For centuries, lavender has been used as a general tonic, sedative, antispasmodic, diuretic, digestive aid, and gas remedy. Lavender tea and essential oil are prescribed to treat common minor ailments such as insomnia, nervousness, fatigue, headaches, nausea, and gas. Its aroma helps to stimulate mental processes to help patients with dementia and alleviate mild to moderate depression.
Mint relaxes the peripheral blood vessels, calms smooth muscle spasms, dries dampness, expels phlegm, and clears the head. It is regarded as an excellent remedy for stomach cramps due to its ability to reduce hypercontractability of the intestinal muscles. It is often added to formulas using laxative herbs, such as cascara sagrada, to prevent intestinal gripe. Peppermint is considered the strongest mint medicinally, though the other mints have medicinal benefit as well. Peppermint has activity against a wide range of pathogens including streptococcus, staphylococcus, and candida.
