Previous Year Question

Asafoetida (Hing) is a natural plant-derived substance obtained primarily from Ferula asafoetida and other species of the genus Ferula. This plant belongs to the Apiaceae Family, formerly known as Umbelliferae. Asafoetida is obtained by drying the milky Latex released from the plant's Tap Root and underground Rhizome. It is an Oleo-gum-resin containing resin, gum, and volatile oil components.

The extraction of Asafoetida involves exposing the upper portion of the mature plant's root and making an incision. The milky exudate gradually thickens and solidifies upon exposure to air. This material is collected and processed into pure or compounded Asafoetida. Its characteristic pungent odour is primarily caused by Sulfur-containing Organic Compounds. It is widely used as a spice in Indian cuisine.

Shilajit is a dark-coloured natural substance obtained from mountainous rock formations. It contains Humic Substances and various mineral components. Scientific studies have examined the possible contribution of biological residues to its formation, but it is not considered a substance obtained directly from a tree. Tincal is a naturally occurring mineral form of Borax, with the chemical formula Na₂B₄O₇·10H₂O. It is used in glass manufacturing, ceramics, and various industrial processes.

Important Scientific Clarification: Although the question uses the term tree, Ferula asafoetida is actually a Perennial Herb, not a true tree. Therefore, the intended distinction is between plant-derived substances and substances obtained from other natural sources. In 2020, CSIR-IHBT initiated experimental cultivation of Asafoetida in the Lahaul Valley of Himachal Pradesh. Previously, India depended mainly on imports from Afghanistan, Iran, and Uzbekistan to meet its commercial requirements.
