Kill Kudzu trees

Kudzu - Pueraria lobata

-No picture available-




Kudzu is a perennial climbing plant that climbs up to 31 meters high and has a shade that can grow to be as big as an adult.
The hairy and tightly intertwined stems have three-leaved leaves up to 18 cm in size. Long legumes emerge from the purple, fragrant flowers. The plant grows an incredible 30 cm per day (comparison: bamboo, the fastest growing land plant on earth, grows up to 80 cm per day). This enables it to overgrown entire houses and cars for a few days. In the USA it has become a very dreaded weed, as can be seen from impressive videos from well-known video platforms.
In winter, Kudzu dies completely above ground. The energy stored in the roots helps the plant to sprout again early in the spring. To destroy them, the entire rhizome has to be removed (which is almost impossible). In the US, Kudzu is currently suffocating around 7 million acres under a thick, green blanket. It can overgrow entire trees there and thereby kill them.


The plant originally comes from China, the Orient and areas in Eastern Asia. It is seldom grown in Java.
It has successfully been released into the wild in the southeast of the USA and South Africa. There kudzu grows along the streets, railroad tracks, climbs fences, telephone poles, sparse forests and abandoned houses.


Kudzu has been used in traditional Chinese medicine (TCM) for centuries. The first written mention of the plant as a medicine is in the ancient herbal texts by Shen Nong (around 100 BC).
Initially, the Kopou bean was grown as an ornamental plant at the Centennial Exposition in Philadelphia, Pennsylvania in 1876. Due to its high protein content, it has long served as a welcome fodder plant since 1920. When it was recognized in 1930 that it could be used against soil erosion and for nitrogen fertilization, it was cultivated extensively. In 1940, farmers were given about $ 8 per acre of land as an incentive to grow and propagate this plant. The project took on a life of its own naturally and kudzu quickly became a dreaded and uncontrollable weed. The US government then stopped funding for the cultivation in 1953 and is now investing $ 500 million annually to stop the plague.

Drugs and ingredients

The roots ("Ge gen") and flowers ("Ge hua") are used as medicinal products. In addition to the isoflavones genistein, daidzin and daidzein, anthraquinone also occurs there.
Furthermore, the aboveground parts of the plant contain many proteins. The edible root is starchy.

Properties and effects

The herb should taste sweet, have a cooling and strengthening effect. It improves skin breathing, relieves pain, relieves cramps, lowers blood pressure and sugar levels, and calms the digestive system. It also has an antipyretic and sweat-inducing effect.
Recently, the plant was introduced to research circles as a very safe and effective drug for alcohol addiction. The previous drugs against alcohol addiction interfere with the breakdown of alcohol and can cause the formation of toxins. However, kudzu reduces the cravings for alcohol.
Daidzin and Daidzein are also said to greatly reduce the desire to consume cigarettes. The substances bind to the receptors in the brain to which nicotine also binds. This will reduce the need for nicotine.
Daidzin is also believed to be a good drug for preventing cancer and leukemia. Animal studies with mice suggest that kudzu is beneficial for post-menopausal symptoms such as high blood pressure and type II diabetes.


The Chinese healing arts used P. lobata for a long time with alcohol abuse.
In addition, the roots are used there against flu, fever, thirst with diabetes, headache and muscle pain, stiff neck, allergy, migraine, measles that have not yet fully broken out, nausea, vomiting and diarrhea, flatulence, angina pectoris and pain caused by high blood pressure.
As is usual with butterflies, the plant is in symbiosis with nitrogen-fixing root bacteria. In this way, the plant with its large root system contributes to the fertilization and consolidation of the soil. Furthermore, it is an excellent fodder plant and, due to its rapid growth, its yield can only be compared with the soy plant.
The ground root can be used in the kitchen to thicken sauces.
The large leaves and the pleasantly fragrant flowers make kudzu an attractive ornamental plant.


There are now many different preparations available with different combinations and concentrations of active ingredients. Therefore, attention must be paid to the package insert. The plant is not listed as a prescription drug, so it can be used cautiously for self-medication.
Between autumn and spring, the roots can be harvested, freshly pressed into juice or dried and pulverized. The flowers are collected before they are fully opened.
About 3-15 grams of the root boiled for 40-60 minutes per day is a traditional dose. However, this preparation should take some getting used to.


As a semi-winter hardy cultivated plant on well drained soils in a sunny location. It does not tolerate dry or waterlogged soils.
Propagation is done by sowing (distance 1 m between the rows, 15-25 seeds per 20 cm, up to 1.3 cm deep) or by dividing the roots in spring. The seedlings can withstand temperatures of -7 ° C until the third pair of leaves appears. Lowerers can be made during the growing season. So that the seeds germinate better, they should be soaked for a few hours beforehand.
You should be very careful that the plant cannot spread uncontrollably. Otherwise you may have a very large and permanent weed problem.
