What is pueraria/ kudzu?


Pueraria,the other popular name is Kudzu.It is a fast-growing vine native to the subtropical regions of China and Japan. The stems that can grow to 20 m (60 ft) in length with extensive roots, the leaves contain 3 broad oval leaflets with purple flowers and curling tendril spikes.

And the plant is a vine. Under the right growing conditions, it spreads easily, covering virtually everything that doesn’t move out of its path. Kudzu was introduced in North America in 1876 in the southeastern U.S. to prevent soil erosion. But kudzu spread quickly and overtook farms and buildings, leading some to call to kudzu "the vine that ate the South.”

Kudzu’s root, flower, and leaf are used to make medicine. It has been used in Chinese medicine since at least 200 BC. As early as 600 AD, it was used to treatalcoholism.

A crude extract of Radix puerariae suppresses the free-choice ethanol intake of ethanol-preferring golden Syrian hamsters due to two of its isoflavones, daidzin and daidzein. This root extract was found to contain 15% ~ 30% puerarin as the main constituent and smaller amounts of the related isoflavonoids 3'-hydroxypuerarin, 3'-methoxypuerarin, 6''-xylosylpuerarin, daidzin, genistin, daidzein and genistein.

3. Pueraria Flower Extract 5:1

extracts from the dried flower of Pueraria thomsonii on blood ethanol and acetaldehyde levels in humans consuming alcoholic beverages. The extracts of Pueraria thomsonii had no influence on blood ethanol and acetaldehyde concentration in humans. However, the extracts increased the elimination rate constant of blood acetaldehyde, although they had no effect on the elimination of blood ethanol in humans. These results suggest that Pueraria thomsonii promotes the elimination of blood acetaldehyde in humans. The present study clinically suggests that a modest stimulatory effect of Pueraria thomsonii on the elimination of blood acetaldehyde may passively mitigate acetaldehyde toxicity, such as flushing, palpitation, headache, etc., associated with excessive alcohol intake.
