40 Years of Herbal Mastery

Holistic Approach to Healing

Herbal remedies might seem old school but modern science backs what our grandparents knew – plants are powerful. Used the right way, plants can help the body heal itself and keep us on track to stay well. This holistic cycle of healing and restoring balance in the body is core to what we do.

Wellness Done Well

We expect our formulas to perform everyday magic. Every bottle is steeped in decades of knowledge, innovation and expertise that is Harker’s so you can live well, and get back to well when everyday health is challenged.

From Our Home to Yours

We’ve come a long way from when Malcolm Harker, our founder, brewed herbal tonics for friends and family from his home. Our friends and family now stretch through generations and to far-flung places. But wherever you are, we're here to help and quick to send wellness straight from our home to yours.

Reviews from our valued customers

I’m a runner and struggle with persistent mucus in my chest. I keep this in my bag always – one swig and I’m away.

My 3 year old daycare child pretty much never gets sick. Being able to make it into gummies is always a hit too.
