Kudzu is a fascinating plant whose health-supporting properties deserve far more attention than they currently receive. This is particularly true for individuals who are working to overcome unhealthy habits, as kudzu root has traditionally been one of nature's most valued allies in that area. But that is just one of its many benefits — this ancient Asian legume also supports cardiovascular health, hormonal balance, and overall wellbeing.
What Is Kudzu
Kudzu (Pueraria lobata), also known as Japanese arrowroot, is a vigorous climbing plant belonging to the legume family. It can grow up to 12 metres in height and is native to Japan and Southeast Asia. The parts of the plant most valued in herbal medicine are the root and, to a lesser extent, the leaves.
Kudzu has been used in traditional Chinese medicine for over 2,000 years — records of its therapeutic applications date back to at least 200 BC. In the 19th century, the plant was introduced to the United States, where it was initially cultivated as animal fodder due to its extraordinarily fast growth rate. It was only much later that scientists identified the bioactive compounds that make kudzu such a valuable ingredient in modern supplements. The most important of these are the isoflavonoids puerarin, daidzein, daidzin, and genistein — plant compounds with a wide range of biological activities.
[tip:Kudzu is one of the fastest-growing plants on Earth, capable of growing up to 30 centimetres per day under ideal conditions. In the American South, it is sometimes called "the vine that ate the South" because of how rapidly it spreads.]
Properties and Traditional Uses of Kudzu Root
Support for Reducing Alcohol Consumption
Perhaps the most talked-about property of kudzu root in recent years is its traditional and research-supported role in helping to reduce alcohol intake. The flavonoid compounds found in kudzu — particularly puerarin, daidzein, and daidzin — are believed to work through two complementary mechanisms.
First, some researchers suggest that kudzu may influence the way alcohol is metabolised in the body, potentially slowing certain enzymatic processes. Second, and perhaps more interestingly, the isoflavonoids in kudzu may support the natural production of serotonin and dopamine — neurotransmitters associated with feelings of wellbeing and satisfaction. By contributing to a balanced mood, kudzu may help reduce the desire for stimulants. In one widely cited study, participants who took kudzu extract for seven days reduced their alcohol consumption by approximately 40% compared to baseline levels.
Kudzu root is also valued for its broader supportive role during this process. It provides natural carbohydrates and minerals, supports the nervous system, and contributes to healthy digestive function — all of which may be beneficial for individuals working toward healthier lifestyle choices.
[note:While kudzu shows promising results in supporting reduced alcohol consumption, it is not a standalone treatment for addiction. It should always be used as a complement to professional guidance and support, never as a replacement.]
Cardiovascular and Blood Pressure Support
In traditional Chinese and Japanese medicine, kudzu has long been used to support cardiovascular health. The isoflavonoids in the root may contribute to maintaining healthy blood pressure levels already within the normal range and support overall heart function. Additionally, the antioxidant properties of these compounds help protect cells from oxidative stress caused by free radicals.
Menopause and Hormonal Balance
Kudzu is also gaining attention for its potential role in supporting women during menopause. Like other isoflavone-rich plants such as red clover and soy, kudzu contains phytoestrogens — plant-based compounds that can interact gently with oestrogen receptors in the body. This mild oestrogenic activity may help support comfort during the menopausal transition, particularly when it comes to hot flushes, mood fluctuations, and maintaining healthy bone density.

Digestive and Respiratory Comfort
Traditional Asian medicine has also employed kudzu root to support digestive comfort, ease occasional nausea, and promote respiratory wellness during seasonal challenges. While these traditional uses have not been as extensively studied as kudzu's effects on alcohol consumption, they speak to the remarkable versatility of this plant and the depth of its history in herbal medicine.
How to Use Kudzu Root
In China and Japan, kudzu has traditionally been consumed as a powdered root infusion or as a dried alcoholic extract. In modern supplement form, it is most commonly available as capsules or tablets, which offer a convenient, standardised way to incorporate kudzu into your daily routine.
For capsules and tablets, a typical serving is 2–4 tablets taken with a meal, though you should always follow the specific dosage instructions on the product packaging. Kudzu root starch (kudzu powder) is also available and can be used as a culinary ingredient — it works well as a thickening agent and can replace other types of flour in cooking.
Regarding duration of use: when taken as a general wellness supplement, kudzu can be used on an ongoing basis. When used specifically to support healthier lifestyle habits, supplementation periods of several months or longer may be appropriate, ideally under the guidance of a healthcare professional.

Contraindications and Safety
While kudzu is generally well-tolerated, certain groups should avoid supplementation or consult a healthcare professional before use:
- Pregnant and breastfeeding women — due to insufficient safety data in these populations
- Individuals with hormone-sensitive conditions — such as endometriosis or thyroid disorders, as kudzu contains phytoestrogens that may influence hormonal balance
- People taking anticoagulant medications — kudzu may interact with blood-thinning drugs
Possible side effects are uncommon but may include mild nausea or itching. As with any herbal supplement, sourcing is important — always choose products from reputable manufacturers who test for purity and contaminant-free raw materials. This ensures you can benefit from kudzu's properties while minimising any risk associated with low-quality plant material.
