Testimonials

It sorted out a raw itch issue that I have had for months. Dr prescribed salve couldn't heal it, numbing spray wouldn't stop the itch. Skin Healing salve did both while mending the skin. Absorbs quickly. Not oily. Healthy smell. Magic!

Amanda

Magic

I've been using the remineralising tooth powder for quite some time with amazing results. My gums have not only stopped bleeding, but with it my teeth have become very, very strong. The cavities between my teeth seemed to have decreased as well, which I can literally feel when I floss.

Ute

Outstanding experience

Cornelia’s easy teaching style caters for all types of learners. We got to see, taste, touch, smell and hear about the plants. She is very knowledgeable and seems to enjoy sharing her wisdom. Very enjoyable day.

Rob

Very enjoyable day

I've sown two lots of cover crop seeds now to try and retain moisture over summer. They're germinating within 3 to 4 days, growing quickly - up to 20cm within 2 weeks I estimate. All seed types are vigorous. I've given 2 bags away as gifts.

Anne Carrie

Fast Germination

I've been on medication for about 2 months now for ongoing respiratory issues. This tea is the only thing that has given me relief and helped with my cough and excess mucus. I highly recommend and have been sharing with family also. I've just ordered 2 more packets.

Djana C

Finally some relief!

Last night I took an acute dose of Health Elixir. BAM I had the best sleep, which is rare for me, 65 and various health issues. Honestly, this is a brilliant product. I love it. I have just taken the cap off the Elderberry Syrup; it smells delicious. Thank you so much for your incredible products and your beautiful integrity.

Incredible stuff

I love attending Korukai workshops. Yesterday was my third workshop, which I enjoyed with my friend and her friend as well! Informative, fun, interactive, and so worthwhile! I appreciated learning the skills of natural cheese making, sharing an incredible meal and time with a great group of people.
