Yes, all Hey Sister! products are regulatory approved. A world first!

We are the first company in the world to have researched, grown and granted regulatory approval for the active ingredient in Hey Sister! the ancient traditional medicine botanical, Khaya senegalensis.

The Hey Sister! active ingredient formulation known as Khapregesic® is now entered onto the Australian Register of Therapeutic Goods.

Khapregesic® contains an ancient traditional medicine plant called Khaya senegalensis (pronounced: Ky-yar sen-ee-gal_en-sis), also known as Khaya (pronounced: Ky-yar).

Khaya is the active ingredient, and comes from sustainably-grown, Certified-Organic Australian plantations.

Khapregesic® is 100% Australian Grown and Made in Australia with NO offshore processing.

Our Life range of products also contain added vitamins and minerals specifically selected to support each stage of life.

In addition to its pain-relieving action during menstruation*, clinical observational studies show that Khapregesic® can ease mild anxiety*, and other associated symptoms such as abdominal cramping, brain fog, bloating and mild diarrhoea*. 

*Traditionally used in western herbal medicine to: [PERIOD] relieve menstruation pain, reduce occurrence of abdominal bloating, relieve symptoms of mild anxiety, reduce mood swings associated with premenstrual tension, [MENOPAUSE] reduce occurrence of menopausal symptoms, relieve symptoms of mild anxiety, reduce heavy menstruation (during peri-menopause). Always read the back of the pack and if symptoms persist, seek the advice of a healthcare professional.

For best results, we recommend starting Hey Sister! 2–3 days before your period begins, if you can. This helps manage PMS symptoms such as anxiety and mood swings, and gets a head start on inflammation — a major cause of period pain. If you're unsure when your period will start, begin taking Hey Sister! at the first sign of symptoms.
