Zinc is an important trace mineral. This element is second only to iron in its concentration in the body.

Zinc is a mineral that is essential for a healthy immune system, production of certain hormones, wound healing, bone formation, and clear skin. It is required in very small amounts, and is thus known as a trace mineral.

Quercetin is a major flavonol, one of the almost 4,000 flavonoids (antioxidants) that occur in foods of plant origin, such as red wine, onions, green tea, apples, berries, and brassica vegetables (cabbage, broccoli, cauliflower, turnips). It is also found in Gingko biloba , St. John's wort, and American elder. It mainly occurs in plants as glycosides, such as rutin (quercetin rutinoside) in tea. Quercetin and rutin are used in many countries as vasoprotectants and are ingredients of numerous multivitamin preparations and herbal remedies. They occur mainly as glycosides, i.e. linked with various sugars. It is uncertain to what extent dietary flavonoid glycosides are absorbed from the gut. Flavonoids, dietary components in vegetables, fruits and beverages, may protect against coronary heart disease, stroke and cancer. However, the ability of the body to absorb (bioavailability) these compounds is questionable. Quercetin and other flavonols have a wide variety of biological effects, but the scientific evidence for use in prevention or treatment of disease is weak. Quercetin has been considered as a therapy for cardiovascular diseases, high cholesterol, cancers, diabetic cataracts, inflammation, ischemic injury, chronic prostatitis, chronic venous insufficiency, gastrointestinal ulceration, hepatitis, allergies, asthma, viral infections and hay fever. Review of the literature shows several studies on the association with risk reduction for coronary heart disease and stroke, cancers and a few studies on other medical conditions. However, there is not strong evidence to support for any of these associations.

Danshen ( Salvia miltiorrhiza ) is widely used in traditional Chinese medicine (TCM), often in combination with other herbs. Remedies containing danshen are used traditionally to treat a diversity of ailments, particularly cardiac (heart) and vascular (blood vessel) disorders such as atherosclerosis ("hardening" of the arteries with cholesterol plaques) or blood clotting abnormalities. The ability of danshen to "thin" the blood and reduce blood clotting is well documented, although the herb's purported ability to "invigorate" the blood or improve circulation has not been demonstrated in high-quality human trials. Because danshen can inhibit platelet aggregation and has been reported to potentiate (increase) the blood-thinning effects of warfarin, it should be avoided in patients with bleeding disorders, prior to some surgical procedures, or when taking anticoagulant (blood-thinning) drugs, herbs, or supplements. In the mid-1980s, scientific interest was raised in danshen's possible cardiovascular benefits, particularly in patients with ischemic stroke or coronary artery disease/angina. More recent studies have focused on possible roles in liver disease (hepatitis and cirrhosis), and as an antioxidant. However, the available research in these areas largely consists of animal studies and small human trials of poor quality. Therefore, firm evidence-based conclusions are not possible at this time about the effects of danshen for any medical condition.

Zinc formulations have been used since Ancient Egyptian times to enhance wound healing, although the usefulness of this approach is only partially confirmed by clinical data of today. Zinc is necessary for the functioning of over 300 different enzymes and plays a vital role in an enormous number of biological processes. Zinc is a cofactor for the antioxidant enzyme superoxide dismutase (SOD) and is in a number of enzymatic reactions involved in carbohydrate and protein metabolism. Its immunologic activities include regulation of T lymphocytes, CD4, natural killer cells, and interleukin II. In addition, zinc has been claimed to possess antiviral activity. It has been shown to play a role in wound healing, especially following burns or surgical incisions. Zinc is necessary for the maturation of sperm and normal fetal development. It is involved in sensory perception (taste, smell, and vision) and controls the release of stored vitamin A from the liver. Within the endocrine system, zinc has been shown to regulate insulin activity and promote the conversion thyroid hormones thyroxine to triiodothyronine. Based on available scientific evidence, zinc may be efficacious in the treatment of (childhood) malnutrition, acne vulgaris, peptic ulcers, leg ulcers, infertility, Wilson's disease, herpes, and taste or smell disorders. Zinc has also gained popularity for its use in prevention of the common cold. The role for zinc is controversial in some cases, as the results of published studies provide either contradictory information, and/or the methodological quality of the studies do not allow for a confident conclusion regarding the role of zinc in those diseases.

Saw palmetto ( Serenoa repens , Sabal serrulata ) is used popularly in Europe for symptoms associated with benign prostatic hypertrophy (enlargement of the prostate). Although not considered standard of care in the United States, it is the most popular herbal treatment for this condition. Historical use of saw palmetto can be traced in the Americas to the Mayans who used it as a tonic, and to the Seminoles who took the berries as an expectorant and antiseptic. Saw palmetto was listed in the United States Pharmacopeia from 1906 to 1917, and in the National Formulary from 1926 to 1950. Saw palmetto extract is a licensed product in several European countries. Multiple mechanisms of action have been proposed, and saw palmetto appears to possess 5-α-reductase inhibitory activity (thereby preventing the conversion of testosterone to dihydrotestosterone). Hormonal/estrogenic effects have also been reported, as well as direct inhibitory effects on androgen receptors and anti-inflammatory properties.
