Ushak (Camphor) in Ayurveda

Botanical Name

Cinnamomum camphora (L.) J. Presl

Family

Lauraceae (Laurel family)

Description

Ushak, commonly known as camphor, is a medium-to-large evergreen tree that grows up to 20–30 meters in height. The bark is rough and brownish, while the leaves are glossy, ovate, and emit a distinctive camphoraceous odor when crushed. The tree produces small white flowers and round blackish fruits. Camphor is extracted from the wood of the tree, which undergoes a distillation and crystallization process to yield the white crystalline substance.

In Ayurveda, camphor has been valued for centuries due to its therapeutic properties and aromatic essence. It is also considered a sacred ingredient in many rituals and ceremonies, symbolizing purity and divinity.

Occurrence

The camphor tree is native to East Asia, particularly China, Japan, and Taiwan. However, it is also cultivated in India, especially in the Himalayan regions and southern parts of the country like Kerala and Tamil Nadu. The tree thrives in tropical and subtropical climates with well-drained soil.

The therapeutic properties of camphor are attributed to its chemical composition, which includes:

• Camphor (C10H16O): The main active compound, responsible for its aroma and medicinal effects.
