Daisy Herb Description - Drug Interactions, Dosage and Some of its Useful Properties
Common Trade Names
Several chemical compounds are derived from the fresh or dried flowers and leaves of Bellis perennis, a common perennial herb.
The flower heads contain saponins, tannin, organic acids, an essential oil, bitter principle, flavones, and mucilage.
Daisy is claimed to have anti-inflammatory and astringent properties.
The Iroquois Indians used the daisy as a GI aid. It has also been used as a mild analgesic, an antidiarrheal, an antispasmodic, an antitussive, an astringent, and an expectorant. When used as an infusion, daisy was reported to treat arthritis, catarrh, diarrhea, hepatic and renal disorders, and rheumatism and to act as a blood purifier. Few data are available to support these claims.
The plant also has reportedly been used externally in compresses and bath preparations for treating skin disorders, wounds, and bruises.
Traditional uses suggest the following doses:
Infusion: 1 tsp of dried herb steeped in boiling water for 10 minutes and taken t.i.d.
Tincture: 2 to 4 ml P.O. t.i.d.
Contraindications And Precautions

Although daisy has been used as food in some parts of the world, pharmacologic effects are largely undocumented. Use with caution.

Although no known chemical interactions have been reported in clinical studies, consideration must be given to the pharmacologic properties of the herbal product and the potential for exacerbation of the intended therapeutic effect of conventional drugs.

Although the daisy has a long history of anecdotal safety, no clinical data exist to substantiate the claims for medicinal purposes. Moreover, its chemical components have not been well described. Subsequently, medicinal use of daisy cannot be recommended.
