Tang Kuei Root

Traditional Uses

Supplements and moves blood, moistens intestines, regulates menses, for Headache due to deficiency of blood, chest and abdominal pain, constipation, amenorrhea, menorrhalgia, functional bleeding

Scientific Research

(1) Uterus-regulating purpose: Tang Kuei has both stimulating and inhibiting actions on uterine muscles. Experiments indicate that its non-volatile water-soluble compounds stimulate uterine muscle, while its volatile oil inhibits uterine muscle, producing a relaxing action. Therefore, to cause the uterus to contract the herb should be decocted for a long period of time to get rid of the volatile oil. If the uterus is to be relaxed then the herb should be put into the decoction later (that is, the other herbs should be decocted first for some time before tang-kuei is added and it should be boiled over a low flame to prevent loss of the volatile oil). Animal studies show that the uterus upon being pressed will exhibit irregular contractions, but after ad-minstration of tang-kuei the uterus will contract regularly. This means that tang-kueican regulate the function of the uterus and that is most probably the mechanism of tang-kueiís ability to treat menorrhalgia. Mice given feed containing 5% tang-kuei have higher DNA (deoxyribonucleic acid) content in their uteri, have higher glucose metabolism, and thus have a higher multiplication rate of uterine tissue.
(2) Purpose on metabolism and secretion: Mice fed with 5% tang-kuei feed have a higher metabolic rate, and show an increase in oxygen consumption by the liver. Though the vitamin B12 content is low in tang kuei, the vitamins may nevertheless be responsible for its hematinic action. The extract protects the liver and prevents a decrease in liver sugar in mice with acute hepatitis induced by carbon tetrachloride. In experiments with mice, the herb acts against vitamin E deficiency, which may be related to its fetus-stabilizing purpose.
(3) Sedative purpose: The volatile oil inhibits brain activity, thus having the purpose of sedation.
(4) Diuretic purpose: Tang-kuei promotes urine excretion.
(5) Antibacterial purpose: In vitro, it inhibits Bacillus dysenteriae, E. coli. Streptococcus haemolyticus and other bacteria.



Tangerine Peel

Traditional Uses

Regulates chíi, strengthens spleen, dries moisture, transforms phlegm, for Turgid chest and abdomen, vomiting, diarrhea, cough

Scientific Research

(1) The herb is used as a stomachic, expectorant, and antiemetic and can regulate the intestine.
(2) Hemostatic purpose: Both hesperidin and rutin (quercetin) possess vitamin P-like activities that strengthen capillaries and decrease bleeding.
(3) Antibacterial purpose: In vitro the extract inhibits staphylococci.
(4) Other purposes: The extract increases blood pressure, stimulates the heart, inhibits gastrointestinal and uterine activities, and slightly inhibits urinary excretion.



Trichosanthes Fruit

Traditional Uses

Moistens the lungs and intestines, resolves phlegm, for Thirst due to febrile disease, jaundice, diabetes, mastitis, sore throat

Scientific Research

(1) Antibacterial purpose: In vitro, it inhibits Escherichia coli, typhoid bacteria, and dysentery bacteria.
(2) Anticancer purpose: Animal studies indicate that it has definite inhibitory actions but not a high inhibitory rate on tumors and ascitic carcinoma.



Trichosanthes Root

Traditional Uses

Cleanses heat, moistens dryness, discharges pus, disperses swelling, promotes secretion of fluids, quenches thirst, for Thirst due to febrile disease; jaundice, diabetes, mastitis, hemorrhoids, sore throat, swelling

Scientific Research

(1) Blood sugar-lowering purpose: Clinical studies indicate that diabetic patients taking a decoction containing trichosanthes as its main ingredient have markedly lowered blood sugar levels.
(2) Anticancer purpose: In vitro it inhibits cancer cells.
(3) Abortifacient purpose: In mainland China, trichosanthes has recently been used-clinically to induce abortion.



Tubuo Angelica Root

Traditional Uses

Removes wind-dampness, promotes circulation of meridians, expels dampness, for Headache due to common cold, aching and pain in the loins and knees, arthralgia due to dampness, wind, and cold, pruritis, convulsive pain in the hands and feet

Scientific Research

(1) Tranquilizing and sleep-inducing purposes: Oral administration or i.p. injection of the extract in mice and rats produces sedating and sleep-inducing actions.
(2) Analgesic purpose: Experiments using the hot-plates methodshow that it has analgesic purposes on mice.
(3) Antiarthritic purpose: It reduces inflammation of the joints induced by formaldehyde in rats.
(4) Hypotensive purpose: Injection of the extract into anesthetized dogs orcats dilates their blood vessels and reduces their blood pressure.



Unripe Bitter Orange Fruit

Traditional Uses

Moves ch'i, dissipates accumulations, for Accumulation of phlegm in the hypochondraic region, chest pain, accumulation in the chest, feeling of fullness, pain in upper abdomen, retention of undigested food, constipation

Scientific Research

(1) Stimulation of gastrointestinal functions: The extract markedly inhibits extirpated rabbit intestines and the gastrointestinal system of anesthetized dogs, but it stimulates gastrointestinal motor activities in humans (this explains why clinically the extract is used to increase digestion).
(2) Contraction of the uterine muscle: The extract stimulates the rabbit uterus and rabbit extirpated uterus by increasing the tonicity and contraction of the uterine muscle.
(3) Purgative purpose: This purpose is thought to be related to the flavonoid content of the aqueous extract.
(4) Other purposes: The aqueous extract increases blood pressure. At low dosages, it increases contraction of extirpated toad heart, while at high dosages it decreases contraction. The aqueous extract slightly inhibits urinary excretion in anesthetized dogs and induces contraction of toad blood vessels.



Unsalted Fermented Soybean

Traditional Uses

Dispels exterior symptoms, relieves fidgets, for Febrile disease, headache, chills and fever, fidgeting, fullness in the Chest

Scientific Research

Stomachic purpose: The enzyme-like activities help digestion an tonify the stomach.
