There are many good brands out there. I order online from various places. I first ordered the raw herb to make tea from China when I was first diagnosed with cancer. The tea was very strong and I drank too much in the beginning and made myself short of breath. (The herb goes after the iron in the blood cells and essentially dissolves the skin of the cell in the process.)

But that is exactly how it helps vanquish the cancer by doing the same thing to the cancer tumors (which crave iron) by dissolving the skin of the tumors, exposing the tumors, which then surprisingly triggers our immune system to recognize it as an invader and attack it.

Since I understood exactly how this herb would work, I was expecting this and when I got breathless, I stopped drinking the potent tea and switched to a smaller capsule dose.

The brands I've take are:

Swanson Full Spectrum Artemisia Annua, or

Absorb Health Artemisinin capsules, or

Biovy Artemisimax Artemisia Annua capsules

Let me know how it goes for you.
