Preparation and Dosage

⚠ Due to its alkaloid content, broom should only be used under the supervision of a qualified herbalist or healthcare provider.

  • Kidney Disease: Use with caution in individuals with impaired kidney function.

Energetics (Traditional Medicine Perspectives)

Modern Research

Studies confirm Cytisus scoparius’s cardiovascular effects, diuretic properties, and potential applications in regulating blood pressure, though caution is required due to its alkaloid content.

Broom remains a valuable herb in traditional medicine, particularly for circulatory and kidney health, but must be used with caution due to its potent alkaloids.
