Traditional use: Used extensively by Native American peoples and early midwives to stimulate uterine contractions, regulate menstruation, ease labor, and treat rheumatism and urinary tract complaints. 

Potential benefits: Caulosaponin and methylcytisine may exert uterotonic and antispasmodic effects; historically, they have been considered useful for menstrual irregularities and pelvic inflammatory conditions in herbal practice.

Warnings: Strictly contraindicated in pregnancy except near term under professional supervision; linked to neonatal heart failure, stroke, and toxicity; may cause chest pain and elevated blood pressure—not for self-prescription.
