== Dose ==

== Important Formulations ==

* ''Ajamodarka''
* ''Ajmodadi churna''
 
== Current Availability ==
Available
 
== Major Phytoconstituents ==
The pharmacological efficacy of ''Trachyspermum ammi'' is predominantly attributed to its essential oil content, which ranges from 2% to 5%. The primary active constituent is '''thymol''' (accounting for 35% to 60% of the oil), accompanied by p-cymene, γ-terpinene, α-pinene, β-pinene, and carvacrol.
 
== Therapeutic Efficacy & Modern Scientific Research ==
Modern pharmacological evaluations and clinical studies validate many of the traditional claims associated with *Trachyspermum ammi*. Its core therapeutic domains include:
 
=== 1. Gastrointestinal and Carminative Activity (''Deepana'' & ''Pachana'') ===
* '''Traditional Use:''' Used for *Gulma* (abdominal lump), *Adhmana* (abdominal distention), *Aruchi* (anorexia), and *Sula* (colic pain).
* '''Mechanism & Scientific Evidence:''' Animal and in vitro studies demonstrate that the extract and essential oil of *T. ammi* exhibit significant anti-spasmodic (anticholinergic-like) and smooth-muscle relaxing properties. The carminative action is primarily mediated by thymol, which stimulates the secretion of gastric juices, enhances metabolic activity, and relieves flatulence and intestinal colic.<ref name="Tharakan2014">Tharakan, S. T., et al. "Evaluation of spasmolytic and bronchodilator activities of Trachyspermum ammi." Journal of Ethnopharmacology.</ref>
 
=== 2. Antimicrobial and Antifungal Efficacy (''Krumiroga'') ===
* '''Traditional Use:''' Employed in *Krumi roga* (parasitic and microbial infections).
* '''Mechanism & Scientific Evidence:''' *T. ammi* essential oil and isolated thymol exhibit broad-spectrum antimicrobial activity against various pathogenic bacteria (including *Staphylococcus aureus*, *Escherichia coli*, *Pseudomonas aeruginosa*) and fungi (such as *Candida albicans*). The high phenolic content disrupts microbial cell membranes, causing leakage of intracellular constituents.<ref name="Khosravi2009">Khosravi, A. R., et al. "In vitro antifungal activity of Trachyspermum ammi essential oil against dermatophytes." Mycoses.</ref>
 
=== 3. Respiratory Support (''Hikka'' & Bronchodilation) ===
* '''Traditional Use:''' Used in respiratory distress, asthma (*Swasa*), and cough.
* '''Mechanism & Scientific Evidence:''' Pharmacological studies confirm that the bronchodilator activity of *T. ammi* is comparable to standard reference drugs (like theophylline/atropine). The relaxation of tracheal chains by thymol and carvacrol facilitates easier airflow, validating its traditional use in obstructive airway diseases.<ref name="Boskabady2014">Boskabady, M. H., et al. "Bronchodilator and anticough effects of Trachyspermum ammi." Research Reports.</ref>
 
=== 4. Antioxidant and Anti-inflammatory Properties ===
* '''Mechanism & Scientific Evidence:''' *T. ammi* seeds possess significant free-radical scavenging abilities due to their high concentration of phenolic compounds. In vivo anti-inflammatory models show that extracts can reduce acute and chronic inflammation, partly by inhibiting inflammatory pathways and prostaglandin synthesis.<ref name="Javed2012">Javed, I., et al. "Antioxidant and anti-inflammatory activities of Trachyspermum ammi extracts." Phytotherapy Research.</ref>
