Salai Guggul Tree | The Aravali’s Ayurvedic Gift


During the hiking trips in Jaipur, I have come across unusual trees & plants. I have shared these in numerous posts on this blog like Dhok tree, Thor Danda, and Sickle Bush. While Dhok is one of the most widely found trees in the Aravali hills surrounding Jaipur, there is another interesting tree that I want to share in this post. The Salai Tree. I have witnessed this tree over the last few years but could never obtain its name until a few months ago. During one of the hikes, I came across this tree with peeling bark.


This prompted me to find out more about the tree. I have seen it in different seasons, but I find it fascinating in winters when it is all bare devoid of leaves.

Salai can grow till 1100-1200 m elevation.

Salai can be found in diverse deciduous forests along with Dhau and Babool species especially in forests of Madhya Pradesh. The tree tolerates large temperature variations ranging from 0 to 45 C.


Aravali Hill Range

Based on my observations, the Salai tree can be easily observed on slopes & ridges of Aravalis in dry deciduous climate. Schist & quartzite stones form Aravali hills near Jaipur, adapts & grows considerably in such conditions. It can survive in most depleted & shallowest soil where most tree would find hard to survive. The other tree that survives in such conditions is Dhok or Anogeissus Pendula tree. The following is a picture of the Salai trees from the Aravali hill range near Jaipur.


Salai remains a moderate to large size tree. The bark is usually thin. Being one of the hardiest trees, it can survive forest fires, and animals don’t present a threat. Tenacity is one of its features. It requires no special care or excess water to endure the harsh climate like the Aravali hill range. Here is a picture of the Salai Guggul tree during the hikes in Jaipur during the monsoon season.
