Traditional Use & History

White clover has a folk tradition, similar to but lighter than its relative red clover, as an anti-inflammatory and wound-healing remedy and mild expectorant, and modern research on its isoflavones and phenolics has additionally investigated antioxidant, kidney-protective and liver-protective activity.[30, 32, 33]

Preparations

Infusion (flower/leaf)[30]

Dried flower and leaf infused in hot water as a traditional mild tonic and expectorant tea.

Safety, Cautions & Contraindications

Safety note[30, 32, 33]Caution

Generally very safe as a food and in moderate herbal use. Cyanogenic glucosides present in very small amounts - not significant in normal food or tea use. Isoflavones are phytoestrogens (as in red clover) - same precautions apply in hormone-sensitive conditions. Well tolerated by most people.

Safety note[30, 32, 33, 34]Info

Duke (2002) does not include a dedicated entry for white clover (Trifolium repens) in the Handbook of Medicinal Herbs, Second Edition.
