Herbalist tips

Reformulated with Siberian Ginseng and Ashwagandha for
stress resilience. The Adrenal Tonic has been updated to include
two cornerstone adaptogenic herbs: Siberian Ginseng and
Ashwagandha. Together, these botanicals help support adrenal
function, stress adaptation, and sustainable energy for modern
busy lifestyles.

Supports:
• Stress response and resilience
• Energy and endurance
• Adrenal and nervous system balance

This is an original Malcolm Harker tonic. Malcolm recommended:

  • Taking this tonic straight, or added to 50ml of boiled water as a tea
  • Avoiding mucus forming foods such as gluten, egg-white, chocolate, dairy, polyunsaturated oils and regular table salt
  • Adopting gluten-free grain foods, whole foods (greens, fruits nuts, seeds), unprocessed coconut oil and Celtic & NZ Sea Salt with Kelp

    With all his tonics, Malcolm also recommended using Intestinal Cleanse for 1-2 weeks to reduce parasite populations. By reducing the load on the body of parasites, the body is able to use nutrients from food and the active ingredients in his tonics more efficiently.

After 3 days I've got my energy back, more relaxed and less stressed.

Being a Mum of three and a fitness instructor, I'm very busy and was starting to feel like I couldn't cope. Highly recommend.

View Our Ingredients Glossary
Licorice

Licorice

Glycyrrhiza glabra

One of the most widely used and trusted herbs in traditional medicine, licorice is also available in Germany as an over-the-counter medicine. It contains glycyrrhizin, reported to have anti-inflammatory and antimicrobial activities as well as being up to 50 times sweeter than cane sugar. It is also reported to promote a healthy adrenal response to stress. Used for respiratory infections, digestion and healthy mood.

Giant Kelp

Giant Kelp

Macrocystis pyrifera

Giant kelp is a nutrient dense superfood. Not only does it have a particularly high iodine content, giant kelp is rich in vitamins, minerals, antioxidants and alginates (a form of dietary fibre). Macrocystis pyrifera is the largest of the seaweeds, growing up to half a metre a day in kelp forests in the Pacific Ocean.

Siberian Ginseng

Siberian Ginseng

Eleutherococcus senticosus

An adaptogenic herb used extensively in traditional Chinese medicine (TCM) to support long term exposure to stress, endurance and stamina. In TCM, Siberian Ginseng is used to strengthen the body’s vital energy (Qi) and support resilience to illness. This super plant contains eleutherosides which support the activity of immune cells such as macrophages and natural killer cells. Macrophages act as the Sergeant-Major of the immune system, rallying the troops and leading the charge against invaders. As an adaptogen, Siberian Ginseng helps regulate the body’s stress response by balancing cortisol levels and supporting adrenal gland function.

Rosemary

Rosemary

Salvia rosmarinus

Rosemary contains rosmarinic acid, an antioxidant and anti-inflammatory compound that helps soothe irritation in the airways. It also contains cineoles, a compound with mucus thinning and antimicrobial properties, which supports clear airways and fighting infection. Rosemary leaves contain around 0.05 to 0.5% camphor, which support its use as a decongestant and expectorant.

Ashwagandha

Ashwagandha

Withania somnifera

Traditionally used to support the nervous system, especially to manage stress, sleep, cortisol balance and overall nervous system health. It is considered an adaptogen, meaning it promotes balance in many different systems of the body. This multi-purpose herb has been used in Ayurvedic medicine for more than 4,000 years.
