The root of Pueraria thomsanii Benth, or P. lobata Willd. The Chinese name of this herb is Gegen.
Origin:
The root of Pueraria lobata (Willd.) Ohwi or Pueraria thunbergiana, a perennial deciduous vine, of the family Leguminosae. The kudzu is a fast-growing, woody, somewhat hairy vine that may grow to a length of 18 m in one season. It has large leaves, long racemes with late-blooming reddish purple flowers, and flat, hairy seed pods.
The plant is native to China, where it was long grown for its edible, starchy roots and for a fibre made from its stems. The kudzu was transplanted to North America with the intention of using it to anchor steep banks of soil and thereby prevent erosion. The plant has become a rampant weed in parts of the southeastern United States, however, since it readily spreads over trees and shrubs as well as exposed soil.
Other uses of the kudzu vine are as a useful fodder crop for livestock, as well as an attractive ornamental. Northern winters tend to kill the plant's stems but allow the roots to survive.
The root has been used by the Chinese as an herb. In China, the plant is distributed everywhere in the south and north of China, picked and dug in spring and autumn, sliced, dried in the sun and used when raw or after it is baked.
2.Traditional Chinese Medicine Description:
Kudzu is a coarse, high-climbing, twining, trailing, perennial vine. The huge root, which can grow to the size of a human body, is the source of medicinal preparations used in traditional Chinese medicine and modern herbal products. Kudzu grows in most shaded areas in mountains, fields, along roadsides, thickets, and thin forests throughout most of China. The root of another Asian species of kudzu, Pueraria thomsonii, is also used for herbal products. Kudzu root is high in isoflavones, such as daidzein, as well as isoflavone glycosides, such as daidzin and puerarin. Depending on its growing conditions, the total isoflavone content varies from 1.77-12.0%, with puerarin in the highest concentration, followed by daidzin and daidzein. As is the case with other flavonoid-like substances, the constituents in kudzu root are associated with improved microcirculation and blood flow through the coronary arteries. A widely publicized 1993 animal study showed that both daidzin and daidzein inhibit the desire for alcohol.The authors concluded that the root extract may in fact be useful in reducing the urge for alcohol and as treatment for alcoholism. This has not yet been proven in controlled clinical studies with humans.
TCM classifies it as a sweet and pungent herb with a mild property. It is spasmolytic, antipyretic, secretory, and anti-diarrheal. It is also thought to induce the eruption of measles at the early stage.
Applications:
1. Used for exterior syndromes caused by exopathogens:
Being sweet and pungent in taste, cool in nature and so light as to be able to rise and disperse and enter the spleen and stomach channels, this herb relieves exterior syndromes by means of profuse perspiration and expels pathogenic factors from muscles and skin to reduce fever, so it is often used together with Chinese thorowax root (Radix Bupleuri), skullcap root (Radix Scutellariae), dahurian angelica root (Radix Angelicae Dahuricae), etc., e.g., Chaige Jieji Tang, for the treatment of exterior syndromes caused by exopathogens such as fever-causing stagnation of pathogenic factors, serious fever with light chills, headache with dryness of the nasal cavities, slight thirst with thin and yellow fur; often used in combination with ephedra (Herba Ephedrae), cassia twig and herbaceous peony root (Radix Paeoniae Alba), e.g., Gegen Tang, for exterior syndromes caused by pathogenic wind-cold, such as chills with anhidrosis and pains and stiffness of the nape and back.
2. Used for measles without adequate eruption:
This herb relieves exterior syndromes by dispersing exopathogens, expels pathogenic factors from muscles and skin to reduce fever and promotes eruption, so it can often be used together with skunk bugbane rhizome (Rhizoma Cimicifugae), e.g., Shengma Gegen Tang, for the treatment of initial attacks of measles, attacks of exopathogens on the superficies of the body and measles without smooth eruption; it can also be used together with peppermint, great burdock achene (Fructus Arctii), jingjie (Herba Schizonepetae), cicada slough, etc.
3. Used for thirst due to febrile disease and diabetes due to yin deficiency:
Being sweet and cool, this herb can encourage stomach-qi to rise while reducing fever, with the effect of promoting the production of body fluids to quench thirst and is often used with common reed rhizome (Rhizoma Phragmitis), Chinese trichosanthes (Radix Trichosanthis), windweed rhizome (Rhizoma Anemarrhenae), etc., for the treatment of thirst due to febrile diseases and impairment of body fluids; largely used in combination with black plums, ophiopogon root (Radix Ophiopogonis), Chinese trichosanthes (Radix Trichosanthis), dangshen (Radix Codonopsis Pilosulae), milk vetch root (Radix Astragali seu Hedysari), etc., e.g., Yu Chuan Wan, for the treatment of diabetes due to internal heat.
4. Used for diarrhea or dysentery due to pathogenic heat and diarrhea due to deficiency of the spleen:
This herb can not only clear away and disperse pathogenic heat, but also raise lucid yang in such a way as to encourage the clear yang-qi of the spleen and stomach to rise and achieve the effect of relieving diarrhea or dysentery, so it is often used together with skullcap root (Radix Scutellariae), Chinese goldthread rhizome (Rhizoma Coptidis) and licorice, e.g., Gegen Qin Lian Tang for the treatment of dysentery due to pathogenic heat with undispersed exterior syndromes and the invasion of pathogenic heat into the interior; often used in combination with ginseng, tuckahoe (Poria cocos), licorice, etc., e.g., Qiwei Baishu San, for diarrhea due to deficiency of the spleen.

4.Pharmacology:
A.Coronary and Cerebral Vasodilatory Effects:
The decoction or ethanol extract of Gegen (which contains total flavones, daidzin, and Puerarin) upon being administered to rats intraperitoneally or subcutaneously antagonized acute myocardial ischemia induced by pituitrin. The injection of Puerarin caused a marked increase in the coronary flow and a decrease in vascular resistance. During intravenous injection, the blood flow of the internal carotid and femoral arteries was also increased, though not as markedly as that in the coronary vessels. The inability of reserpine to modify the action of the total flavones and Puerarin on coronary circulation indicates a direct relaxant action on the vascular smooth muscle. Puerarin was more potent than the total flavones. Intravenous injection of Puerarin in anesthetized dogs decreased the heart rate and the total peripheral resistance, slightly decreased the left ventricular work, reduced the myocardial oxygen consumption, and increased the myocardial efficiency. The cardiac output, however, was not significantly altered. These effects were beneficial to the maintenance of equilibrium between myocardial oxygen demand and supply [3]. IV injection of extract of Gegen in anesthetized dogs with acute myocardial infarction induced by ligation of the anterior descending coronary artery caused a significant decrease in blood pressure, a slowing of the heart beat, and a slight decrease in blood flow in the infarcted area. At the same time, it caused no significant change in the arterial blood oxygen, but significant increase in the venous blood oxygen at the coronary sinus and infracted area. The oxygen utilization and consumption, as well as lactic acid content, in both the normal and infarcted areas were markedly decreased. Whereas lactic acid utilization was markedly increased. These results indicate that Puerarin has excellent effects on the metabolism of infarcted myocardium. Injection of total flavones to the internal carotid artery of anesthetized dogs causes a dose-dependent increase in the cerebral blood flow and a decrease in cerebral vascular resistance.
B.Hypotensive Effects:
Pueraria's total flavones can causes hypertensive dogs and normotensive anesthetized dogs to lower their blood pressure. In hypertensive dogs, the pressure response to norepinephrine and the hypotensive effect of acetylcholine could be attenuated by the ethanol extract of Gegen. It has a direct vasodilatory action, which decreases the peripheral vascular resistance. It can also decrease the blood catecholamine level and vascular reactivity. This may be the reason why it can be effectively used for treating migraine headaches.
C.Inhibition of Platelet Aggregation:
ADP-induced rat platelet aggregation was inhibited to different extents by 0.25, 0.5, and 1.0 mg/ml of Puerarin in vitro, and also intravenous injection. At doses of 0.5 ¨C 3.0mg/ml, Puerarin also inhibited (in vitro) aggregation of rabbit and sheep platelets, and those of normal subjects induced by ADP or serotonin. It can also inhibit secretion of serotonin from platelets. This effect is favorable to the prevention and treatment of angina pectoris and myocardial infarction.
D.b-Adrenergic Blocking Effect:
In various isolated tissues with Beta-Adrenergic receptors, this herbal extract exhibited different degrees of significant antagonism against the effect of isoproterenol. This fact suggested that it is a wide-spectrum beta-blocker. The extract of Gegen at doses as low as 15 mg markedly attenuated the stimulant effect of 5 ug of isoproterenol on the isolated heart. Whereas tenfold the above dose had practically no direct inhibitory effect on normal hearts, nor does it influence the cardiotontic effect of digitalis glycosides. The findings suggest that the herb has selectivity to the ¦Â1-receptors. The beta2-receptor blocking action was found to be weak because doses up to 150 mg were required in order to antagonize bronchodilation and peripheral vasodilation induced by isoproterenol.
5.Pharmacokinetics:
Orally administered Puerarin was rapidly but incompletely absorbed in rats. IV injection of this substance was found highest in concentration in the kidney, lower in plasma, liver, and spleen, and lowest in the brain. It was minimally destroyed in the gastrointestinal tract, and it was metabolized in the blood, liver, and kidneys. Also, it can bind to the proteins of liver, kidneys, lungs and plasma. The 24-hour urinary and fecal excretion of the oral dose of Puerarin accounted for 1.85 and 35.7% respectively. The data showed that after administered, it was rapidly distributed and eliminated, with low accumulation.
Properties: Pungent and sweet in flavor, cool in nature, it is related to the spleen and stomach channels.
Functions: Expels pathogenic factors from muscles and skin to reduce fever, promotes eruption, promotes the production of body fluids to quench thirst and invigorates the vital functions to relieve diarrhea.
It is spasmolytic, antipyretic, secretory, and anti-diarrheal. It is also thought to induce the eruption of measles at the early stage;
The herb is used in China to treat fever, headache, stiffness of back and neck, dry mouth in diarrhea or dysentery, and early-stage measles.
Treats angiocardiopathy. A scavenger of reactive oxygen species and inhibitor of LDL oxidation. It has potential effect to prevent atherosclerosis
Oral administration of dried ethanol extract (10,000 to 20,000 mg/kg daily for three days) to mice did not result in any toxic effects. Likewise, no toxic effects were exhibited by the total flavones. The LD50 of the dried ethanol extract in mice was 2000-2120 mg/kg. Oral administration of the ethanol extract (2,000 mg/kg daily) to mice for two months did not cause pathological changes in the solid organs. Likewise, administration of the ethanol extract to hypertensive dogs (2,000 mg/kg daily for 14 days) orally produced no toxic effects either.

7.Clinical Studies:
A.Headache and Migraine:
Symptomatic improvement was achieved in 35 of 42 migraine cases. In hypertensive patients, it improved the cerebral blood flow, lowered the vascular resistance, and shortened the influx time in about 50% of the cases.
B.Hypertension:
The total flavones (100 mg daily in two doses) was given for a course of 2-8 weeks to 222 cases of hypertension with pain and stiffness of the neck. 78-90% of the cases reported relief of neck symptoms. In 90% of the cases remedial effects appeared after one week of administration, persisting for one to two weeks. In some patients there were no relapses during a period of 3 to 9 months after discontinuation of therapy. The treatment alleviated symptoms of headache, dizziness, tinnitus, and numbness of extremities but did not significantly lower the blood pressure.
C.Coronary Disease and Angina Pectoris:
191 cases of coronary disease and angina pectoris were treated with Gegen tablet (each tablet contains 10 mg of total flavones), 3-4 tablets three times a day. This treatment was effective in relief of anginal pain and in improving ECG. Another group of 110 cases of coronary disease were treated with a compound of extract of Puerarin and Crataegi, 90% of them had relief of anginal pain and 43% had marked improvement.
D.Sudden Deafness at Early Stage:
The tablets of the ethanol extract of Gegen (each equivalent to 1.5 grams of crude herb) were used at dose of 1-2 tablets three times a day together with injection of the total flavones 100 mg IM twice daily (and in some cases also supplemented with vitamin B complex) in order to treat 176 cases for a course of one to two months, hearing improvement in 79.5% of the cases.
8.Kudzu Root Modern Researches:
This herb mainly contains flavones, such as daidzein, daidzin, daidzein-4, 7-diglucose glucoside, puerarin, puerarin-7-xyloside, puerarol, xylopuerarin, isoflavonoid glycoside and starch. Kudzu vine root can dilate coronary vessels and cerebral blood vessels and increase the blood flow of coronary arteries.
Total flavone of kudzu vine root can reduce the myocardial oxygen consumption and increase the supply of oxygen. Kudzu vine root can directly dilate the blood vessels to lower peripheral resistance. It can also reduce blood pressure remarkably and alleviate the "nape tension" symptom of a patient with a high blood pressure in a better way. Puerarin can inhibit the platelet aggregation. Kudzu vine root has an extensive blocking effect on beta-receptors. Kudzu vine root also has an obvious antipyretic effect and can also reduce blood sugar slightly.
Updates:
1.Determination of 12 pueraria components by high-performance liquid chromatography-mass spectrometry:
Puerariae radix, a commonly used Chinese herb drug derived from the dried root of legume plant, contains a series of isoflavones as its chief pharmacologically active constituents. Using 12 pueraria components as markers, an LC-UV-MS method requiring less than 60 min, was developed for estimating the quality of pueraria samples within 60 min. Extracts were analyzed using a Cosmosil 5C18-MS column, by gradient elution with an aqueous solution of acetic acid and methanol-ACN at a flow-rate of 1.0 mL/min. Peaks were detected at 254 nm and each peak was identified by LC/MS. The reproducibilities (RSD) of this proposed method, on the basis of peak-area ratios from six replicate injections, were 0.93-1.42% (intraday) and 1.05-1.63% (interday) at a detection limit of 0.12-0.78 microg/mL. Most of the markers used in this study can be classified, respectively, into three major categories, namely, isoflavones, O-glycosidic isoflavones, and C-glycosidic isoflavones. The structures of the compounds were determined from LC-MS fragmentation data and data from the literature.
2.An extract of the Chinese herbal root kudzu reduces alcohol drinking by heavy drinkers in a naturalistic setting:
Background: Of the available medications for treating alcohol-related problems, none are universally effective, and all have side effects that may limit their use. Extracts of kudzu containing a variety of isoflavones have been shown to reduce alcohol drinking in rats and hamsters.
Methods: The present study was designed to test the efficacy of a kudzu extract in a clinical population. Male and female "heavy" alcohol drinkers were treated with either placebo or a kudzu extract for 7 days and then given an opportunity to drink their preferred brand of beer while in a naturalistic laboratory setting. Participants served as their own controls, and order of treatment exposure was counterbalanced. Drinking behavior was monitored by a digital scale that was located in the top of an end table.
Results: Kudzu treatment resulted in significant reduction in the number of beers consumed that was paralleled by an increase in the number of sips and the time to consume each beer and a decrease in the volume of each sip. These changes occurred in the absence of a significant effect on the urge to drink alcohol. There were no reported side effects of kudzu treatment.
Conclusion: These data suggest that an extract of this leguminous plant may be a useful adjunct in reducing alcohol intake in a naturalistic setting.

4.Antitumor activity of spinasterol isolated from Pueraria roots.:
We purified phytoestrogens from Pueraria root (Pueraria mirifica from Thailand and Pueraria lobata from Korea), which is used as a rejuvenating folk medicine in Thailand and China. Dried, powdered plant material was extracted with 100% ethanol and further separated by concentration, filtration, and thin layer silica gel chromatography. Using the fractions obtained during separation, we first investigated their cytotoxicity in several cancer cell lines from various tissues. The ethanol-extracted components (PE1, PE4) had significant antiproliferative effects on breast cancer cell lines, including MCF-7, ZR-75-1, MDA-MB-231, SK-BR-3, and Hs578T. Second, we compared these results with the cytotoxic effects of known flavonoids, sterols, and coumarins from Pueraria root. The known compounds were not as effective, and occurred in a different polarity region on HPLC. Third, further separation resulted in the isolation of eight different components (Sub PE-A to -H). One of these, PE-D, affected the growth of some breast cancer cell lines (MCF-7, MDA- MB-231) in a dose- and time-dependent manner, as well as the growth of ovarian (2774) and cervical cancer cells (HeLa). Finally, a transfection assay showed that this component had an estrogenic effect similar to 17beta - estradiol, which activates both estrogen receptor alpha (ERalpha) and ERbeta. The NMR analysis determined that spinasterol (stigmasta-7, 22-dien-3beta-ol) is an active cytotoxic component of Pueraria root.
5.Analysis of the estrogenic components in kudzu root by bioassay and high performance liquid chromatography.:
The estrogenic activity of the Chinese herb kudzu root was investigated by a recombinant yeast screening assay (YES). Isoflavones are the main components in the plant, of which puerarin is the most abundant one. The kudzu root extract was separated into four fractions according to the polarity. The crude extract and its sub-fractions, except the water fraction, showed clear estrogenic activity and the potencies were in the range of 10(-3) to 10(-1)g/l. The ligand potency was used to compare the estrogenic activity of these fractions. The crude extract and its sub-fractions were further analyzed by high performance liquid chromatography (HPLC) to correlate the activity and the active components. Bioassay and chemical analysis showed that theoretical estrogenic activity expressed as equivalent 17beta-estradiol concentration or the cumulative effects are comparable to that experimentally determined by YES. The results showed that the high content of isoflavones as well as the high estrogenic activity could make kudzu root extract an interesting candidate for hormone replacement therapy.
6.Quantitative analysis of phytoestrogens in kudzu-root, soy and spiked serum samples by high-pressure liquid chromatography.:
A sensitive and reliable HPLC method that allows simultaneous quantification of phytoestrogens extracted from kudzu-root and soy preparations, and serum samples has been developed. Kudzu-root and soy preparations were mixed with 5 microg flavone and 15 microg rutin (internal standards) and the phytoestrogens were extracted by using solid-phase (C18) extraction cartridges. Blank or spiked serum samples were extracted by using either C18 cartridges or trichloroacetic acid-methanol extraction. The extracts were analyzed by the HPLC equipped with a reverse-phase (250 x 4 mm, C18) column and UV, diode-array or MS detector. A linear gradient of acetic acid and acetonitrile provided excellent separation of glycoside and aglycone-phytoestrogens from kudzu root and soy preparations. The C18 cartridge extraction of serum yielded excellent recovery of both glycoside- and aglycone-phytoestrogens, while the trichloroacetic acid-methanol extraction yielded excellent recovery of glycoside but poor recovery of aglycone compounds. UV and MS detectors were suitable for phytoestrogen analysis in plant and serum samples, while the diode-array detector was suitable for generating the UV absorbance curve for phytoestrogens.
