Names and identification

Language	Name
Sanskrit	Mishreya
Latin/Botanical	Foeniculum vulgare Mill.

Key Phytochemical Constituents

• Trans-anethole (60-90% of essential oil - primary active)
• Fenchone
• Estragole (methyl chavicol)
• Alpha-pinene
• Limonene
• Beta-myrcene
• P-cymene
• Camphene
• Flavonoids (quercetin, kaempferol)
• Phenolic acids (rosmarinic acid, chlorogenic acid)

How does it work?

• Antispasmodic and carminative mechanism through trans-anethole blocking calcium channels in GI smooth muscle, reducing intestinal spasm and gas-related pain
• Estrogenic activity mediated by trans-anethole and its polymers (dianethole, photoanethole) acting as weak estrogen receptor agonists, supporting galactagogue and menstrual regulation properties
• Hepatoprotective mechanism through antioxidant-mediated reduction of hepatic lipid peroxidation and enhancement of glutathione and catalase enzyme levels

Which traditional uses are supported by research?

These summaries come from the source notes, which do not name the studies behind them.

• Traditionally used as Deepana-Pachana (appetite and digestion promoter). Clinical and pharmacological studies have reported carminative and digestive activity.
• Traditionally used as Stanyajanana (breast milk promoting). Clinical studies have reported increased milk production in breastfeeding women.
• Traditionally used for pediatric GI complaints. Randomized clinical trials have reported antispasmodic activity in infantile colic.

Recent safety updates

• GRAS (Generally Recognized as Safe) by FDA; however, estragole component has raised genotoxicity concerns - EMA recommends limiting estragole exposure; fennel products should be standardized for estragole content
• Phytoestrogenic effects warrant caution in hormone-sensitive conditions (breast cancer, endometriosis); potential interactions with anticoagulants and ciprofloxacin; allergic cross-reactivity possible in patients with celery/carrot/mugwort allergy (celery-birch-mugwort-spice syndrome)
