About Us

INSEASON HERBALS NZ was formulated in April 1990 and is the brand name manufactured and used by Medical Herbalist/Naturopath David Harrison. At that time, David was running a busy clinic and manufacturing his ORIGINAL and UNIQUE FORMULAS for his clients. It wasn't long before retailers recognized the INSEASON HERBALS range as the most comprehensive one of its kind in New Zealand and have stocked it ever since.

David is a well qualified Natural Therapist with a Bachelor of Naturopathy, a Diploma in Medical Herbalism and has over 25 years clinical experience. David has specialized in formulating, prescribing and manufacturing herbal medicines.

He also lectured at the Waikato Institute of Technology (WINTECH Natural Therapies Programme) over a 15 year period, as well as at the Waikato Centre for herbal studies for 2 years.

We are also regularly consulting with other natural health care companies regarding formulations and product production as part of our Contract Manufacturing Service.
