Students of Ayurveda and botany alike often look for a clear reference entry on Khadira, one that sets out the botanical name, the plant family and the classical profile in a single place. This monograph from Art of Vedas gathers those details in the format of a study note, describing the tree, the parts used and the way the older texts characterise the herb.
Botanical name and family
The botanical name of Khadira is Acacia catechu, a species also written in modern taxonomy as Senegalia catechu. It belongs to the family Fabaceae, the great legume or pea family, within the mimosa subfamily. In common usage the tree is known as the catechu or cutch tree, and in northern India it is widely called Khair. It is a thorny, deciduous tree of dry forests across South Asia, recognised by its feathery bipinnate leaves and its hard, dark red heartwood.
Classical synonyms
Ayurvedic materia medica lists Khadira under several descriptive synonyms, each pointing to a feature of the tree. It is called Raktasara for the red core of its wood, Dantadhavana for the long tradition of using its twigs as a chewing stick for the teeth, and Gayatri among the older poetic names. These synonyms are a useful memory aid, because they encode the appearance and the customary uses of the plant within the name itself.
Parts used and classical profile
The principal part used is the heartwood, the dense inner timber known in tradition as Sara. The bark is also used in some preparations. From the heartwood comes the traditional catechu, a concentrated extract long familiar in South Asian custom. In the classical framework, Khadira is described as follows:
- Rasa (taste): Tikta (bitter) and Kashaya (astringent)
- Guna (qualities): Laghu (light) and Ruksha (dry)
- Virya (potency): Sheeta (cooling)
- Part used: heartwood, and to a lesser extent the bark
- Traditional grouping: among the herbs classically valued for the skin and for oral care
This profile explains why Khadira threads through so many classical formats. Its bitter and astringent tastes, its light and dry qualities, and its cooling potency together account for its long association with the complexion and with the care of the mouth and teeth.
Where Khadira appears in practice
Because the same wood that gives the tooth-stick tradition also flavours classical oral-care oils, Khadira sits naturally beside Arimedadi Thailam, the oil of the Acacia group used in daily mouth care. As a powdered botanical it belongs to the wider world of classical Churnam, and readers building a herb library often keep everyday powders such as Haritaki powder on hand alongside it. For the skin side of the tradition, our companion article on Khadira for the skin sets out the complexion customs in detail. To understand the powder format itself, see the guide to classical Churnam, and to follow Khadira into oral care read the Arimedadi Thailam guide.
Who studies Khadira
This entry is written for the curious reader and the student rather than for self-treatment. People turn to Khadira by interest and tradition, drawn to its bitter, astringent character and its place in the classical repertoire. Individual constitution, or Prakriti, shapes how any botanical suits a routine, and a qualified Ayurvedic practitioner is the right guide for personal use.
