A source of fiber for linen fabric since ancient times, the slender flax plant (Linum usitatissimum) also boasts a long history as a healing herb. First cultivated in Europe, the plant’s brown seeds were regularly used to prepare balms for inflamed skin and healing slurries for constipation. Today, flaxseeds–also called linseeds–are best known for the therapeutic oil that is derived by pressing them. Rich in essential fatty acids, or EFAs, flaxseed oil has earned a solid reputation for treating a range of ailments, from heart disease to lupus.
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.
One of the world’s most popular supplements, the chemical coenzyme Q10 has generated great excitement as a heart disease remedy and a cure for countless other conditions. The body naturally produces this compound, which has been dubbed “vitamin Q” because of its essential role in keeping all systems running smoothly. In fact, the scientists who identified coenzyme Q10 in 1957 initially honored its ubiquitous presence–it’s found in every human cell and in all living organisms–by naming it “ubiquinone.” Small amounts are also present in most foods.
