She had wisely trimmed her fingernails to avoid injuring her own skin, but as she sat in my office she continuously rubbed one part of her body or another with the ball of her thumb in order to relieve the itching. Tracy was in her 20s and accompanied by her mother. Although I could see […]
The minerals zinc and copper can be purchased as single products, but there’s good reason to consider a combination product that pairs the two.
Zinc blocks the absorption and enhances the excretion of copper when taken over time. So, when zinc is recommended long term (over many months) for any condition–from arthritis to prostate problems or even Alzheimer’s–it’s important to get some copper as well. A combination product will help prevent a copper deficiency and the anemia that can develop as a result.
Recently, the delicious and easy-to-crack nuts from the walnut tree (Juglans regia) have received a lot of attention because of their rich stores of omega-3 fatty acids and other healing nutrients. But for centuries herbalists have recognized the healing properties of another part of the walnut tree–its pointy green leaves.
Scientists identified vitamin E about 80 years ago, but only in the past few decades has its power as an antioxidant been revealed and fully appreciated. What this means is that you’ll have to get far more than the government-established RDA for this vitamin to benefit from its ability to stave off disease and enhance overall health. Unfortunately, most foods containing vitamin E–nuts, vegetable oils and margarine, for example–are high in fat. So to get the protective punch of vitamin E without adding fats to your diet, you need to seriously consider taking supplements.
In the eighteenth century, seasoned sailors found that by sucking on lemons they could avoid scurvy, a debilitating disease that often developed during long voyages when fresh fruits and vegetables were scarce. When the lemon’s key nutrient was formally identified in 1928, it was named ascorbic acid for its anti-scurvy, or antiscorbutic, action. Today ascorbic acid is widely known as vitamin C.
This famed vision-enhancing nutrient was isolated in 1930, the first fat-soluble vitamin to be discovered. The body acquires some of its vitamin A through animal fats. The rest it synthesizes in the intestines from the beta-carotene and other carotenoids abundant in many fruits and vegetables.
Omega-6 fatty acids belong to a group of “good” fats called polyunsaturated fatty acids. Unlike such “bad” fats as cholesterol and saturated fatty acids (which contribute to the worsening of a host of ailments including heart disease and other degenerative conditions), omega-6s can actually be beneficial to your health.
Omega-6 fatty acids are one of two types of essential fatty acids (EFAs) that people need to consume to stay healthy. Omega-3s are the other. Both are considered “essential” because the body can’t produce them on its own; it can only get them through foods.
From generation to generation, the majestic oak tree has provided shade on sunny days, timber for furniture-makers and ship-builders, and even food in times of famine. Many Native American tribes relied on its acorns for nourishment.
Not surprisingly, medicinal uses for the oak tree have a long history as well. Of the hundreds of Quercus species found in the northern hemisphere, Quercus alba is most valued in North America for medicinal purposes. Europeans rely more heavily on Quercus robur and Q. petraea.
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.
As its name implies, grape seed extract is derived from the small seeds (and occasionally the skins) of red grapes–the same kind that are pressed to make wine. Used extensively in Europe, grape seed extract is rich in flavonoids, phytochemicals that have antioxidant properties some consider even greater than the old standbys vitamin C and vitamin E. Antioxidants are believed to prevent and control numerous ailments by safeguarding cells against the ravages of unstable oxygen molecules called free radicals.
Flavonoids is the umbrella term given to some 4,000 compounds that impart the colorful pigment to fruits, vegetables and herbs. Also found in legumes, grains and nuts, flavonoids can act as effective antivirals, anti-inflammatories, antihistamines and antioxidants. They’re useful for reducing cancer risk and serve to prevent or treat a wide variety of conditions.
Heralded for its heart-healthy actions, fish oils offer high concentrations of polyunsaturated fats called omega-3-fatty acids. While all fish contain these fats, cold-water fish–salmon, sea bass, tuna, trout, mackerel–are particularly rich sources because of their diet: plankton packed with omega-3s. Interestingly, the colder the water, the more omega-3s in the plankton. Cold-water fish also boast the most potent forms of omega-3s: the essential fatty acids known as eicosapentaenoic acid (EPA) and docosahexanoic acid (DHA). Consumed as part of a fish-filled diet or in supplement form, omega-3s have myriad healing powers.
Evening primrose oil is extracted from the evening primrose plant (Oenothera biennis), a wildflower found in North America, Europe and parts of Asia. The plant’s pale yellow flowers open in the evening–hence its common name–and its seeds bear the special fatty oil that is used in healing today.
When dealing with inflammatory conditions (such as eczema or allergies), there are several good reasons to consider products that combine bromelain, a natural anti-inflammatory derived from pineapples, and quercetin, a plant pigment (or flavonoid) prominent in apples and onions.
From its bristly stems to its blue star-shaped flowers, virtually all parts of the borage plant (Borago officinalis) have been used over the centuries for their healing properties and as a flavoring for foods. As early as the 1600s, Europeans mixed borage leaves and flowers into a wine that was renown for relieving boredom and dispelling melancholy.
