Introduction
Turbud (Operculina turpethum) is a medicinal climbing vine widely used in traditional systems of medicine, especially in Unani and Ayurvedic practices. It is valued for its strong purgative properties and its role in cleansing the body.
Botanical Description
Turbud is a vine plant that spreads along the ground. It exists in two main types:
- One with a black outer root
- One with a white outer root
However, both types have white inner roots.
Stem and Growth
- Each branch is three-angled (triangular)
- The plant spreads through both seeds and creeping branches
- During the rainy season, seeds germinate, and new vines develop
- Branches can also root into the soil and expand the plant further
Leaves
The leaves are:
- Round with slightly pointed tips
- Arranged in pairs along the vine
Flowers and Seeds
- The white variety produces white flowers
- The black variety produces bluish flowers
- Each flower has five petals
The fruit (pod) contains four to five black seeds.
Root and Resin
The root is the most important medicinal part of the plant.
Root Characteristics
- Outer surface: Brown
- Inner part: White when peeled
- Contains a central woody portion
- Taste: Initially bland, later slightly bitter and sharp
A milky juice is extracted from the roots, which hardens into a resin-like substance. This resin is known for its strong medicinal effects, especially as a laxative.
In traditional medicine, the processed root is called “Turbud Majoof Kharashida.” However, in the market, it is sometimes adulterated with other types of wood.
