Cautions & Contradictions
- Oestrogenic activity of isoflavenoids has been studied, with fertility compromising results seen in animal trials (Braun & Cohen, 2010, p. 789).
- “Clover disease” has been seen in animal studies. Characterised by permanent loss of fertility, reduction in uterine response to oestrogen and luteinising hormone. This has not been seen in humans (Braun & Cohen, 2010, p. 789).
- Theoretically phytoestrogens may compete with synthestic estrogens (Braun & Cohen, 2010, p. 789).
- Use in pregnancy is not recommended
- No known contraindications of flower (Braun & Cohen, 2010, p. 785).
- Due to presence of phytoestrogens, the herb should be used cautiously in diseases characterised by high estrogen levels, such as endometriosis or uterine fibroids (Braun & Cohen, 2010, p. 789).
For skin problems, combines well with Yellow Dock and Nettles (Hoffmann, 1990, p. 227)
