Arab doctors in the 9th and 10th centuries called lemon balm the gladdening herb and prescribed it to dispel anxiety and heart palpitations. More recently, a panel of physicians, pharmacologists, and scientists appointed by the German Ministry of Health endorsed the herb for relieving tension, anxiety, and restlessness. There’s also evidence of cognitive benefits. In a small study published in Neuropsychopharmacology, 20 healthy young adults reported increased memory and improved mood after ingesting lemon balm. Another study found similar results among Alzheimer’s patients.
Growing tip: Like peppermint, lemon balm is fast growing. If you plant it in your garden rather than in a pot, be sure to give it a lot of space.
Health Benefits: Dispels anxiety; improves mood
The use of rosemary as a memory enhancer dates back at least to early Western civilization. Greek students wore garlands of rosemary around their heads, and students in Rome massaged their temples and foreheads with the herb prior to exams. According to Jim Duke, the herb can also reduce joint pain. To make a topical ointment, soak rosemary needles in almond oil for two weeks, filter, then rub the oil onto sore joints as needed.
Growing tip: Rosemary is best grown from a plant and performs well in a container.
Health Benefits: Increases memory; reduces joint pain
Used throughout history as a sedative and sleep aid, valerian gets its name from the Latin valere, which means "to be in good health." "Just the smell alone of the sweetly scented plant is enough to put some people out," says fourth-generation herbalist Christopher Hobbs, author of Herbal Remedies for Dummies. Research conducted on 16 insomniacs at Humboldt University of Berlin, in Germany, found valerian extract helped them nod off faster and improved the quality of their sleep.
Growing tip: When valerian is used for medicinal purposes, cut the flowers as soon as they appear (otherwise, they take energy from the leaves). Opt for the Valeriana officinalis variety, which can be used medicinally.
Health Benefits: Acts as sleep aid; has sedative effects
Research conducted at the Allergy Clinic in Landquart, Switzerland, last year found that sage combined with echinacea was as effective as the painkiller lidocaine in relieving sore throat pain. Plus, studies show that the herb’s bacteria-fighting heft makes it a potent breath freshener. To make sage mouthwash, steep 1 tablespoon sage leaves in 1 cup of hot water for 5 minutes. Strain and gargle.
Growing tip: Sage is best started from a plant, because it can take up to a year to establish itself. The best medicinal variety is Salvia officinalis.
Health Benefits: Eases sore throats; freshens breath
To Make a Tea With These Herbs
Pour one cup boiling water over six leaves (for valerian, use 2 T. chopped root). Steep for five minutes, strain and sip.
