fennelA perennial herb that contains fixed oils (e.g., oleic, linoleic and petroselenic acids), flavonoids, vitamins and volatile oils (e.g., anethole, estragole, limonene and pinene).
The seeds are regarded as antispasmodic, antitussive, diuretic, expectorant and tonic, and used for colic, dyspepsia, hernias, nausea and vomiting.
In Western herbal medicine, fennel is regarded as a carminative; the seeds and roots are used to treat tired eyes, gastric discomfort, kidney stones, to increase breast milk and to stimulate the appetite; other uses are similar to those in Chinese herbal medicine.
