Dosage information

In accordance with clinical usage, the correct dose is the "lowest dose required to produce the desired effects (soft-formed and comfortable stool)". This is either 1-2g of the powdered extract or fruit usually standardized to 10-30mg active Sennosides.

Higher doses are used only if the aforementioned lower dose is not effective (it should be noted that senna alexandria is a delayed laxative unlike the immediate effects of caffeine and it may take a few hours to assess whether a dose is effective or not).

Senna alexandria tends to be taken prior to bed in order to time its laxative effect with a morning bowel movement.
