This is a STRONG cathartic (stimulating evacuation of the bowels). It has a griping effect which can be mollified by taking it with ginger. It is habit forming and can weaken the large intestine. It can work well in cleansing the system during fasting and with large quantities of water can be effective in treating fevers (however, not suggested for children.) ONLY in a laxative combination should Senna be used by pregnant women. Senna is useful for constipation, jaundice and worms. We suggest CKLS instead.
