About Senna

Senna (Cassia senna) is a herb used in the Western Herbalism and African Traditional Medicine traditions to help with Constipation, Digestive Issues, Detox, and Weight Loss. The aerial parts and leaves are the parts traditionally used, taken internally.

Botanical background

Senna alexandrina (Alexandrian senna, in Arabic عشرج or عشرق and see below) is an ornamental plant in the genus Senna. It is used in herbalism. It grows natively in lower Egypt, especially in the Nubian region, and near Khartoum (Sudan), where it is cultivated commercially. It is also grown elsewhere, notably in India and Somalia.

Quality tips

When buying Senna, look for: certified organic labelling, clearly stated country of origin, third-party lab testing for heavy metals and pesticides, and a batch expiry date. Standardised extracts offer consistent dosing; bulk dried herbs are more economical for regular use. Avoid very cheap, unlabelled products — quality varies enormously.
