In this post, I’m going to introduce you the sadao tree, scientifically known as azadirachta indic. Outside of Thailand, the sadao tree is also known as the neem tree, it’s Urdu and Hindu name. The sadao is native in India, Pakistan and Bangladesh but today it can be found allover the world. The tree spreads in tropical and subtropical areas with an average annual temperature between 21 to 32 degree Celsius. It is a very resistant and adaptable tree and can, if groundwater is available, survive in very dry areas too. Sadao is a evergreen tree growing usually up to 15 – 20 meter, in rare cases even up to 40 meter. If no water is available for longer times, the tree may shed most of its leaves. The sadao tree’s leaves are like the fah talai jone extremely bitter. In Pakistan the leaves are used to make baths for children with skin diseases and elders use them to control high blood pressure. The leaves can also be burned to keep away mosquito. In Myanmar, Laos, Cambodia and Thailand various bitter tasting meals are prepared with the flowers, leaves and fruits of this tree. Even those meals are not enjoyed by all inhabitants, they are eaten due to their health benefits. The Indian call the tree by various names such as “Sacred Tree” or “Village Pharmacy” and use the trees leaves and flowers for over two thousand years. This ancient natural remedy is used in Asian’s traditional medicines to treat various diseases such as diabetes, viral and bacterial infections, fungal diseases, to expel parasitic worms out of the body. The tree’s products are also used for birth control and as a tranquilizer. In Ayurvedic medicine the tree’s leaves are especially used to treat skin diseases. The sadao tree is not only a big pharmacy, it plays also an important part in organic and non-pesticidal agriculture. A powder is made from the seeds of the tree which is than mixed with water and sprayed onto the crops. The liquid is a repellent and protects the plant from being eaten. The plantation’s insects are simply starving. The sadao liquids also suppresses the baby insects from hatching from their eggs. To be effective, this procedure must be repeated every ten days. As if this wouldn’t be enough, the tree’s products can also be uses as a natural fertilizer. During the process of pressing the tree’s fruits and seeds to produce an oil, there occurs a by-product, the “neem cake”, a natural fertilizer.
