  1. Blond Psyllium
    NatMed
    Blond Psyllium
    Blond psyllium (Plantago ovata) is an herb. Its seed husk is used as a laxative and stool softener and to help reduce cholesterol. Psyllium seed husks absorb water in the stomach and form a large mass. This mass stimulates the bowel in people with constipation. In people with diarrhea, it can slow down the bowel and reduce bowel movements. This mass can also reduce the amount of cholesterol that is absorbed into the body. Blond psyllium is commonly used as a stool softener in people with constipation and hemorrhoids. It is also used for diarrhea, irritable bowel syndrome (IBS), high cholesterol, heart disease, and diabetes. It's used for many other conditions, but there is no good scientific evidence to support most of these other uses.

  2. Hazelnut
    NatMed
    Hazelnut
    Hazelnut is the nut from the hazel tree (Corylus avellana). It is rich in monounsaturated fatty acids and is commonly eaten as food. Hazelnut contains oil, protein, fiber, and antioxidants. The antioxidants in hazelnut might have heart health benefits. People use hazelnut for obesity, high cholesterol, heart disease, dementia, and other purposes, but there is no good scientific evidence to support these uses. Hazelnut is a tree nut. It is considered a major food allergen.

  3. Docosahexaenoic Acid (DHA)
    NatMed
    Docosahexaenoic Acid (DHA)
    Docosahexaenoic acid (DHA) is an omega-3 fatty acid that is found along with eicosapentaenoic acid (EPA) in cold-water fish, including tuna and salmon. DHA plays a key role in the development of eye and nerve tissues. DHA might also reduce the risk of heart and circulatory disease by decreasing the thickness of the blood, reducing swelling (inflammation), and lowering blood levels of triglycerides. People commonly use DHA for high levels of cholesterol or other fats in the blood. It is also used for boosting memory and thinking skills, for helping infant and child development, for certain eye disorders, and many other conditions, but there is no good scientific evidence to support many of these uses. Don't confuse DHA with EPA. They are both in fish oil, but they are not the same. DHA can be converted into EPA in the body in very small amounts. See separate listings for algal oil, cod liver oil, fish oil, EPA, and krill oil.

  4. Sitostanol
    NatMed
    Sitostanol
    Sitostanol is a plant product. It is made from vegetable oils or the oil from pine tree wood pulp, and is then combined with canola oil.

The U.S. Food and Drug Administration (FDA) allows manufacturers of products that contain sitostanol to claim that the product lowers the risk of getting heart disease. There is plenty of evidence that sitostanol lowers cholesterol levels, but so far there is no proof that long-term use lowers the risk of developing heart disease.

  7. Dimethylglycine (DMG)
    NatMed
    Dimethylglycine (DMG)
    Dimethylglycine (DMG) is an amino acid, a building block for protein. The body needs dimethylglycine to function. Dimethylglycine is an essential amino acid, which means that the body cannot make this chemical on its own. It must be consumed in the diet. It is found in grains and meats and can also be taken as a supplement. People use dimethylglycine for aging, athletic performance, memory and thinking skills (cognitive function), and many other purposes, but there is no scientific evidence to support its use.

    Black cohosh (Actaea racemose) is a woodland herb native to North America. The root is used as medicine and is often used for estrogen-related conditions. In some parts of the body, black cohosh might increase the effects of estrogen. In other parts of the body, black cohosh might decrease the effects of estrogen. Black cohosh should not be thought of as an "herbal estrogen" or a substitute for estrogen. People commonly use black cohosh for symptoms of menopause, premenstrual syndrome (PMS), painful menstruation, weak and brittle bones, and many other conditions, there is no good scientific evidence to support most of these uses.

  10. Hops
    NatMed
    Hops
    Hops are the dried, flowering parts of the hop plant (Humulus lupulus), commonly used in brewing beer. They have limited evidence of health benefits. The term "hops" comes from the Anglo-Saxon term "hoppan", which means "to climb." Hops contain many chemicals, including bitter acids, which contribute to its bitter flavor. Some chemicals in hops seem to act similarly to the hormone estrogen and some seem to cause sleepiness. People commonly use hops for anxiety, sleep disorders, restlessness, symptoms of menopause, and many other conditions, but there is no good scientific evidence to support these uses.

Pantothenic acid helps the body utilize carbohydrates, proteins, and lipids. It is also important for maintaining healthy skin. Vitamin B5 is available as D-pantothenic acid, as well as dexpanthenol and calcium pantothenate, which are chemicals made in the lab from D-pantothenic acid. People most commonly use pantothenic acid for pantothenic acid deficiency. Dexpanthenol, a chemical similar to pantothenic acid, is used for skin irritation, nasal swelling, wound healing, and other conditions, but there is no good scientific evidence to support these uses.

  14. Rice Bran
    NatMed
    Rice Bran
    Rice bran comes from the outer layer of rice (Oryza sativa). Rice bran oil is popular as a "healthy oil" in Japan, Asia, and particularly India.

Rice bran might also decrease calcium absorption, which might help prevent certain types of kidney stones from forming. People use rice bran for high cholesterol, diabetes, high blood pressure, athletic performance, and many other purposes, but there is no good scientific evidence to support many of these uses. Don't confuse rice bran with rice bran arabinoxylan compound, or other forms of bran such as oat bran and wheat bran.

  19. Canthaxanthin
    NatMed
    Canthaxanthin
    Canthaxanthin is a dye that is similar to the chemical that makes carrots orange. It occurs naturally and can also be made in a laboratory. People use it as medicine. Canthaxanthin is used to reduce sensitivity to sunlight (photosensitivity) experienced by people who have a rare genetic disease called erythropoietic protoporphyria (EPP). In these people, sunlight can cause skin reactions such as rash, itch, and eczema. Canthaxanthin is also used to reduce sun sensitivity caused by certain medications and other conditions, but there is no good scientific evidence to support these uses. Orobronze (canthaxanthin) is sold in Canada as a nonprescription "tanning pill." In the U.S., the Food and Drug Administration (FDA) has not approved tanning pills containing canthaxanthin. Nevertheless, these products seem to be readily available to people in the U.S. through mail order and tanning salons. In foods, canthaxanthin is used as food coloring and is added to animal feed to improve the color of chicken skins, egg yolks, salmon, and trout.
