Allaeanthus kurzii is a tree in the mulberry family (Moraceae). It grows in parts of South and Southeast Asia, including Myanmar and nearby islands. Many botanists now file the same tree under the name Broussonetia kurzii.
It is best known as a fibre plant rather than a medicine. People stripped the inner bark to make cord, rough cloth and paper. Its name also turns up on broad lists of Asian medicinal plants.
Here is the honest verdict. There are no human trials behind this tree, and no clear, well-recorded folk use for any named illness. Traditional standing is not proof that a plant works, and it is not proof that a plant is safe.
No mechanism is established for this tree. Nobody has shown how it acts in the human body.
Its close cousins have been studied a little. In laboratory work, bark and leaf extracts of paper mulberry (Broussonetia papyrifera) contain prenylated flavonoids. These plant compounds appear to slow some enzymes and some bacteria in test tubes.
That work is not evidence for Allaeanthus kurzii. Different species in the same family can have very different chemistry. Even where a cell study shows an effect, it often does not carry over to people.
You are unlikely to find this plant for sale at all. It is not a standard supplement in Europe, the UK, the US or Australia.
Where it is used, it is used locally and in simple forms:
- Fresh or dried inner bark - Fresh leaves - Bark fibre, which is a craft material, not a medicine
Online sellers sometimes list mulberry family barks under loose or mixed names. That is a real risk. A bag labelled with one Latin name may hold another species.
The clearest historical record for this tree is as a fibre crop, not a cure. Its bark was beaten into barkcloth, cord and paper in parts of Southeast Asia.
It also appears in reference lists of Asian medicinal plants. Those lists record that a plant was named and used somewhere. They do not record how well it worked.
No major written system, such as Ayurveda or classical Chinese medicine, gives this species a settled role. That silence matters when you are judging it.
Stop and see a doctor if you get a rash, swelling, itching or stomach pain after using it.
Get urgent help if your lips, tongue or throat swell, or if you struggle to breathe. Those are signs of a severe allergic reaction.
Also see a doctor if your skin or eyes turn yellow, or if your urine turns dark.
No medicines regulator in the UK, EU, US or Australia has approved this plant as a medicine. In the EU and UK it would likely need novel food clearance before sale as a supplement, and it has none.
