Carum copticum is a small, erect, flowering shrub of the family Apiaceae. Usually growing no more than 1m in height, C. copticum is supported by its stiff, woody stem which is typically glabrous, but can occasionally have minute pubescence. The stems branch heavily in a striation pattern. The thin leaves of C. copticum are distant from one another, pinnately divided, with each section growing from 1cm to 2.5cm in length. In its native habitat, C. copticum blooms between the months of November and March, producing small, white flowers. The flowers exist in terminal compound umbels which can grow to be up to 4cm across. The seeds of C. copticum are strongly fragrant and packed into small, light brown seed pods, which themselves are often mistaken for the seeds. The small seeds inside the pod are dark brown and usually no more than 2mm in diameter.
Carum copticum, or Ajwain, most likely has origins in the Mediteranian area and Egypt. Presently the small amount of cultivation that is done is done in India.
Mainly thymol, with p-cymene, dipentene, alpha and beta pinene, t-terpinene, camphene, myrcene, beta-3-carneen, limonene, carvacrol. Contains the glycocide 6-0-Beta-D glucopyranosyloxythymol, as well as palmitic pertoselenic oleic and linoleic acids. [3][4][5]
The ajwan-ka-phul extracted from Ajwain is almost identical to thymol extracted from Thymus vulgaris. [1] Vitamins include calcium, carotene, chromium, cobalt, copper, iodine, iron, manganese, nicotinic acid, phosphorus, riboflavin, thiamin, and zinc.
Fruit/seed
Also known as Yavani, the medicinal part of this plant is a seed-like fruit that is quite often confused with many other seeds and spices (i.e. celery seed, caraway, etc…) because when dried it resembles an oval, gray seed.3-6 g powder, 126 mg extract. [2]
Pre-clinical
Often used as a spice, C. copticum is known in modern medicine for its bronchodilatory effects, and has been used in the treatment of asthma. In one study, researchers compared the effects of an extract of the herb with both placebo and theophylline in treating asthmatic patients. By measuring the pulmonary functional tests (PFT) of the subjects at regular intervals, the researchers were able to conclude that C. copticum was as effective as the theophylline and more effective than the placebo. [7]
The anti-tussive properties of C. copticum have been reported in pre-clinical settings. One animal study suggested that C. copticum was more powerful than Codeine in this respect and that these properties were not related to carvracol, a constituent of C. copticum previously thought to be responsible for its anti-tussive properties. [8]
Other pre-clinical studies have indicated that C. copticum may have antihypertensive effects as well as analgesic properties as it has been identified as an opiod. [9][10] C. copticum may also possess some anti-diabetic properties.
