What’s the difference?

Syrups

Syrups

High strength liquid herbals that actually taste good. With a max of 6 evidenced-backed herbs in each syrup, every spoonful works hard for your wellness. Formulated in a sweet chicory root fibre base to mask the bitter herbs, these are delicious straight from the spoon or mixed into your favourite drink.

Tonics

Tonics

Malcolm Harker's original range of herbal tonics, keeping us on-the-go for more than 40 years. Each tonic contains up to 20 different herbs and essential oils and are thin liquids, more like tea. They have a strong herbal aroma and medicinal flavour to match. We take these straight or mixed into a shot of water.

Premium Ingredient Sourcing You Can Trust

At Harker Herbals, we’ve spent over 40 years building trusted relationships with leading herbal growers and suppliers—primarily across Europe—who share our commitment to quality, integrity, and sustainability. We only source from partners who meet strict ethical and environmental standards and conduct rigorous quality checks at every stage.

We understand that not all natural ingredients are created equal. Factors like soil health, climate, and cultivation methods significantly affect the potency and purity of medicinal herbs. That’s why we search the globe to find the highest-quality herbal ingredients—grown in ideal conditions to deliver superior therapeutic benefits.

Our premium herbal ingredients are carefully selected and independently tested for authenticity, efficacy, and safety—including checks for heavy metals and pesticides. This ensures every natural supplement we produce is as pure, powerful, and effective as nature intended.

When it comes to your health, every ingredient matters—and we’re committed to delivering nothing but the best.

Harker’s Heritage

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.

We take this every day – straight off the spoon which is super convenient or sometimes we enjoy it in warm water as a hot drink. My toddler loves it too.

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