Melissa

Folk healers in the Middle Ages considered melissa (Melissa officinalis) something of a cure-all, relying on it for everything from indigestion to insect bites. Today, this mint-family member–often called lemon balm because of the citrus-y aroma of its leaves–is still used to prepare healing oils, tinctures, compresses, ointments, teas, and other remedies for a variety of complaints.

Melatonin

Melatonin is a hormone manufactured and released into the bloodstream by the pebble-size pineal gland nestled deep within the human brain. Surprisingly, scientists only became aware of melatonin’s presence in 1958. Children tend to excrete large amounts of this hormone, while older adults produce relatively little. But individual levels of melatonin vary widely. About 1% of the population naturally has quite low levels, while another 1% has levels 500 times above the average.

Marshmellow

Since ancient times, Europeans have relied on the root of the marshmallow plant (Althea officinalis) to concoct cough and sore throat remedies. Interestingly, the “Althea” in the herb’s botanical name comes from the Greek word for “heal” or “cure.” And the plant’s common name–marshmallow–comes from the habitat that it favors: marshes and other damp environments.

Magnesium

Essential for hundreds of chemical reactions that occur in the body every second, the mineral magnesium has received surprisingly little attention over the years. Recent findings, however, suggest that it also has important health-promoting benefits, from an ability to prevent heart disease to a role in treating such chronic conditions as fibromyalgia and diabetes.

Lysine

Lysine is one of numerous amino acids that the body needs for growth and tissue repair. It is classified as one of the nine “essential” amino acids because you need to get it from outside sources such as foods or supplements–in other words the body can’t make it on its own.

Lycopene

Lycopene provides the red color to tomato products and is one of the major carotenoids in the diet of North Americans and Europeans. Lycopene is a prominent member of the carotenoid family. In plants, lycopene is similar to other carotenoids, serving as a light-absorbing pigment during photosynthesis and protecting cells against photosensitization. Interest is growing in lycopene because of the many recent epidemiological studies implicating lycopene in the prevention of cancer and cardiovascular disease. A diet rich in foods containing carotenoids is associated with several health benefits. Lycopene has unique structural and chemical features that may contribute to its biological actions in humans.

Lipotrophic Combination

Nutritional supplements known as lipotropic combinations (or lipotropic factors) are designed to enhance liver function and increase the flow of fats and bile from the liver and gallbladder. By definition, a lipotropic substance decreases the deposit, or speeds up the removal, of fat (lipo=fat, tropic=stimulate) within the liver. Lipotropic combinations are well known in naturopathic medicine but are little used by conventional physicians.

Licorice

Few herbal remedies have been as widely used or as carefully examined over the centuries as licorice (Glycyrrhiza glabra), a botanical member of the pea family that is still widely cultivated in Greece and Turkey. The herb’s key therapeutic compound, glycyrrhizin, is found in the rhizome (or underground stem) of this tall purple-flowered shrub. Hundreds of other potentially healing substances have been identified in licorice as well, including compounds called flavonoids and various plant estrogens (phytoestrogens). Researchers are currently excited about the diverse healing properties of licorice, from its anti-inflammatory abilities to its capacity to soothe stomach upset and control coughs. Even the National Cancer Institute has investigated the medicinal benefits of licorice.

Lecithin and Choline

Lecithin is a fatty substance manufactured in the body and widely found in many animal- and plant-based foods, including eggs, liver, peanuts, soybeans, and wheat germ. Lecithin is often used as an additive in such processed foods as ice cream, margarine, and salad dressings, because it helps blend (or emulsify) fats with water. Lecithin is also available in supplement form.

Lavender

Recognized around the globe for its fresh and heady fragrance, the lavender plant (Lavendula angustifolia), a flowering evergreen shrub native to the Mediterranean region, also boasts a long history in herbal healing.

Romans scented their baths with it (in fact lavare means to wash in Latin), and the Tibetans still make an edible lavender butter to use as part of a traditional treatment for nervous disorders. Today, the essential oil of lavender is widely used across Europe–both topically and internally–for a host of ills, from anxiety to sunburn.

Kava

A member of the pepper family, kava (or kava-kava) is a natural tranquilizer that soothes jangled nerves and eases anxiety with few of the mind-dulling effects of prescription relaxants. Its Latin name, Piper methysticum, means “intoxicating pepper,” and indeed, on the South Pacific islands where it is grown, kava is made into a traditional beverage that is drunk at ceremonies and on social occasions–as alcohol is in other societies–to relax people and induce a sense of well-being.

Ivy Leaf

Many North Americans probably don’t realize that the climbing ivy plant (Hedera helix), so often found in their gardens and yards, has a long history in folk healing. In its native Europe, the plant’s shiny, dark green leaves have traditionally been used for colds and congestion, for fighting fever (by inducing sweating), and for controlling parasites.

Ipriflavone

Ipriflavone (7-isopropoxyisoflavone) is a synthetic derivative of naturally occuring isoflavones, flavonoid compounds found in soybeans and other plants that act like the female hormone estrogen in the body.

For some time, postmenopausal women in Europe and Japan have taken ipriflavone supplements to maintain the density and strength of their bones and to guard against fractures and other complications associated with the bone-thinning disease known as osteoporosis.

Horse Chestnut

Every autumn, the shady horse chestnut tree (Aesculus hippocastanum) produces prickly fruits containing one to three large seeds, or “nuts.” In the 1800s, European doctors figured out that an extract made from these seeds could help treat varicose veins, hemorrhoids, and other disorders caused by fragile veins and sluggish circulation.

Horehound

Ancient Greeks reportedly relied on horehound (Marrabium vulgare) to treat mad-dog bite, which explains the “hound” in this plant’s name. But over time, it has been this herb’s power to control a cough that has made it so popular. Soothing teas, lozenges, and syrups concocted from its wooly leaves and white flowering tops make a cough more productive by stimulating phlegm (mucus) output in the airways. Colds, bronchitis, and other minor respiratory problems often respond to horehound treatment as well.

Herbal Digestive Formula

Naturopathic doctors have long recommended a classic herbal digestive combination (variously known as Robert’s or Bastyr’s Formula) for controlling the intestinal pain and inflammation associated with Crohn’s disease and ulcerative colitis, both inflammatory bowel diseases.

Herbal Decongestant

Several herbs can help relieve the swelling and stuffiness that make sinusitis, the common cold, or other respiratory complaints so uncomfortable. Most of these herbs work by opening up clogged nasal passages to ease breathing. And while they can certainly be bought and used individually, a blend of these botanicals provides the unique healing qualities of many different herbs–in just a single pill.

Hawthorn

Hawthorn (Crataegus oxyacantha), a rose family member popularly planted along hedges to deter trespassers with its prickly branches, has heart-healthy properties that ancient Greeks and Native Americans recognized centuries ago. Its modern reputation as a healing agent dates to Victorian times, when an Irish physician’s secret heart formula was ultimately revealed to contain a tincture made from the bright red berries.
