Kumarahou tea

Approximately 1 teaspoon of kumarahou added to a pot of boiling water.

Allow to boil (don't use a microwave!) for 1 minute and then simmer for 10 minutes, the liquid will turn a yellow/golden colouring - almost like honey. 

We will let you into a little secret - it doesn't taste great on its own!  however, we suggest mixing it with honey or raw brown sugar.


Drink 2 cups a day for a full week and then each alternative week. 

Kumarahou is sold in 30 gram and 100g packets of dehydrated leaves, enough for 3 month’s supply and approved for export from New Zealand to most countries.



Store in a cool dry place away from direct sunlight.

About Kumarahou

Making Wairakau, the rongoa, is an excellent way of extracting important antioxidant substances such as flavononids and polyphenols, glycosides, antimicrobial tannins, mineral salts and some vitamins (such as niacin and B12, which are not affected by the heating process), in their most absorbable forms. 5 are Native to NZ. FAMILY: Rhamnaceae Buckthorn family.


misspellings: kumeraho, kumerahou, kumarahoe, kumaraho

I got my first packet of tea from a friend in Wakefield Finished the packet and bought yours as my ashma was better. I have this flue right more and a bit pissed as it was doing so well. Hope it goes away soon. Will keep having taking a cup a day.
