There is not much information on the dosage and administration of “Indigo naturalis” itself.
The following is a description of “Indigo naturalis” as used in Chinese herbal medicine.
**************************************************************
Ao Kaoru (Chintai)
Ao Kaoru contains indigos and other compounds, and the active anti-cancer ingredient is indirubin. Aonori can enhance the mononuclear macrophagino-hypophagic function and humoral immune function of animals with cancer.
It can exert its anti-cancer effect by improving the immune function of the body. In clinical trials, there have been relatively many studies on the treatment of chronic leukemia, which have shown a positive therapeutic effect. When combined with radiation and chemotherapy, the therapeutic effect can be further enhanced and side effects can be reduced.

I also inquired at a Korean herbal medicine store I know about the dosage, and they said 4g three times a day, once a day. I am using 2g three times a day, once a day, so doubling the dosage does not seem to be a problem.
In my case, I did not need to increase the dosage because I got sufficient effect, and I will reduce it in the future as I see fit.
