| Herbs | Herbs may be used as dried extracts (capsules, powders, teas), glycerites (glycerine extracts), or tinctures (alcohol extracts). Unless otherwise indicated, teas should be made with one teaspoon herb per cup of hot water. Steep covered 5 to 10 minutes for leaf or flowers, and 10 to 20 minutes for roots. Tinctures may be used singly or in combination as noted. The high doses of single herbs suggested may be best taken as dried extracts (in capsules), although tinctures (60 drops four times per day) and teas (4 to 6 cups per day) may also be used. |
| Herniated Disc | A patient with a herniated or "slipped" disc can have leg and/or back pain. The most common complaint is that of shooting pain down one or, uncommonly, both legs. The pain will typically travel from the back or buttocks to below the knee. The second possible symptom is back pain. Patients often report a history of back pain that occurred before the actual herniation. Many patients recall an episode of their back "going out" or of significant pain that resolved over a period of days with rest and was usually not accompanied by leg pain. |

| Hormone-altering Drugs | Drugs that act by influencing your naturally-occurring hormone levels. Examples include Metformin, which affects insulin levels; Tamoxifen and Arimidex which affect estrogen levels; LHRH agonists which affect testosterone levels; and propylthiouracil (PTU) and methimazole(MTZ) which affect thyroid levels. |
| Hormones | Chemical substances secreted by a variety of body organs that are carried by the bloodstream and usually influence cells some distance from the source of production. Hormones signal certain enzymes to perform their functions and, in this way, regulate such body functions as blood sugar levels, insulin levels, the menstrual cycle, and growth. These can be prescription, over-the-counter, synthetic or natural agents. Examples include adrenal hormones such as corticosteroids and aldosterone; glucagon, growth hormone, insulin, testosterone, estrogens, progestins, progesterone, DHEA, melatonin, and thyroid hormones such as thyroxine and calcitonin. |
| Hot Flash | See Hot Flashes. |
| Hot Flashes | A sudden wave of mild or intense body heat caused by rushes of hormonal changes resulting from decreased levels of estrogen. Hot flashes can occur at any time and may last from a few seconds to a half-hour. They are due to blood vessel opening and constricting, and are a symptom of menopause. A hot flash is a feeling of warmth, sometimes associated with flushing that spreads over the body and sometimes followed by perspiration. |
