When should you not consume Black Goji?

At the first glance, Black Goji sounds too good to be true.

Many of the information floating around the internet about Black Goji are not based on scientific research and proper testing. While the chemical composition of Black Goji is true, it should not be considered as a silver bullet against cancer or against ageing.

In Chinese medicine, goji berries are both a medicine and a poison. Too much of a good thing can be a bad thing. Goji berries and in particular the Black Goji, “raise blood temperature” (温热). Their consumption is not advised for people who are ‘hot-blooded‘, i.e. they also exhibit typically ‘hot-tempered’ behaviour. This will in turn lead to excess fire in their liver (内热) and brings about an imbalance linked to pains in the head, neck and sinus regions.

How do you consume Black Goji?

Many people make an infusion with Black Goji and after drinking the infusion, eat the berries.

You must note that the OPC content is destroyed if the water temperature is too high. Water temperature must not exceed 60 degree celsius or 140 fahrenheit.

Black Goji also releases different colours when infused in different types of water.
Normal boiled tap water will release a blue infusion.
When you add boiled mineral water, Black Goji will release a purple hue after interacting with the additional trace elements in the water.
