Kumerahou was used topically in traditional Māori herbal medicine or Rongoa as healing agent for wounds and abrasions. Kumerahou is rich in sapponins which produce a soapy lather when mixed with water, hence the plants colloquial name ‘Gumdigger’s Soap’.

This extract is made from premium Kumerahou harvested in Kawhia, Waikato by Mana Wahine who carry a lineage of Mātauranga Māori on how to approach and harvest botanicals in a sustainable and respectful process. 

Organic Bioactives have harnessed the power of Harakeke leaf using their proprietary PlantæXtraction™ technology allowing you to include it into many types of formulation with ease.

The PlantæDerMX® range is sustainably obtained by PlantæXtraction™, Organic Bioactive's proprietary innovative, clean beauty multi-step extraction technology. This innovative combination of multiple scientifically proven green extraction methods is a low-speed, cold crushing & pressing system that physically disrupts and breaks open plant cell walls under reduced exposure to air and heat. This low impact, high yield method retains the plant vitality and efficiently released vitamins, antioxidants, enzymes, and minerals.

PlantæDerMX Kumerahou Extract

This is one of the products I was looking forward to trying especially. It doesn’t grow in the South Island and I have heard how good it is for soothing itchy skin. It did not disappoint! Very pleased how soothing it is mixed in with other extracts in the PureNature shampoo and conditioner bases.

Kumerahou Extract

Thank you for your prompt response and delivery, so as to experience Western and Cultural Rongoā and to justify whether or not rongoā has a place in this modern society. Kumerahou and Kawakawa have been used frequently by myself and other members of my whānau and whānau whānui for many years as a child growing up in the Te Tai Tokerau Rohe, there are many other rongoā, however, these are the two I will advocate for, currently.

Kawakawa Extract and Kumerahou Extract

I mix 50/50 Kumerahou Extract with Kawakawa Extract, which I use as rongoā


50ml Mane

For maintaining my blood pressure.


Prescribed Candestar 8ml.

Doctor has agreed to this changed as I have a appointment on the 30.03, where he will retest blood pressure, We will then be able to either justify the use of the rongoā or go bake on Candestar 8ml. Either way, I am keen at the outcome of this test either remaining on 50/50 Kawakawa/Kumerahou or Candestar. Either outcome I will be healthier.

Ngā mihi
