Sandra Walsh has a diploma in Clinical Herbal Medicine from Canterbury College of Natural Medicine and a Bachelor of Science in biology and chemistry from Canada. She has been a member of New Zealand Association of Medical Herbalists & Natural Health Council of New Zealand.

Her training includes the use of medicinal herbs, nutritional supplements, diet, lifestyle advice, and Bach flower remedies. 

She and her family emigrated from Canada to New Zealand in 2003. They arrived with four kids, thirteen suitcases, and no keys. A grand adventure. Her interest in alternative health care began in 2001 with the birth of her Down Syndrome girl. The doctors had no information or advice except for “Get ready for the Special Olympics." A naturopath in Canada guided the family helping their girl as she became stronger and more alert.

Imagine Sandra's surprise to find the Canterbury College of Natural Medicine right here in Christchurch. Affordable (well, almost!) and local. An international qualification. So off she leapt into alternative health care. Another grand adventure.

It’s been an absolute joy to study and practice herbal medicine for Sandra. Eczema, psoriasis, acne, surgical scars, itchiness, digestive complaints, cancer, and more have been tended to in clinic. Products have been tailored to specific complaints and personalised for each person. They have been tried and true, helping deal with the symptoms while correcting the underlying cause. 

Herb Nerd NZ products have come from that clinical experience. Our Healing Cleanser used to be called Acne Cleanser. But then it started helping with rashes and facial scars. It's name changed to Healing Cleanser. The same with our Moisturiser. It was for Damaged Skin. Moisturiser is a far better name! 

Our products are made from organic, natural ingredients. The herbs are carefully chosen. Sandra has the privilege of wild crafting herbs on a local organic farm. We order from reputed suppliers & growers. We infuse the oils. This takes time - sometimes up to twelve weeks.

Sandra handcrafts in small batches, drawing on herbal experience & knowledge, clinical observations, a science background in chemistry & biology, and a deep love of herbal medicine. We are excited to share them with you. They are pretty darn fine products.


We have an extensive dispensary onsite. We offer herbal tinctures, professional grade supplements including MediHerb, Orthoplex, Eagle, Metagenics, Researched Nutritionals, & Thorne along with over eighty individual dried herbs.

Our dried herbs are sourced from reputed growers and herbal supply companies where they are quality tested for purity and efficacy. We choose organic, organically grown, or spray-free herbs. There are some ready made blends in store and online ranging from Just Chamomile to more complex blends such as Menopause, Pregnancy, or Worry Wort (for anxiety.) Our blends have been used in clinic for many years with great success. Because the herbs of a professional grade, our teas can be used up to three times and still retain their medicinal value. They are packaged in biodegradable, econic kraft bags. 

All of our supplements and tinctures are tested for purity, quality and ensure the correct herb and the proper part of the herb is used. Even the containers are tested for safety. Because they are professional grade, the number of tablets prescribed will normally be lower than the supplements you find at retail or online outlets. 

Tinctures are the alcohol extracts of herbs which are potent, effective medications. A tincture is customised for your health concern and is an easy way to take several herbs in one go. Because it is made just for you, the remedy fits you rather than the other way around. The usual dose is twice a day.

You are always welcome to drop in and have a look around. Maybe you have a question or two. Either way, it's always lovely to see you.
