Tian Ma/ Gastrodiae Rhizoma granules - How much?

There are a lot of variables when it comes to dosage of herbs. The concentration of the formula, the form (power, pill, raw herbs, etc), the age and weight of the patient, whether its a single herb or a mixed formula, and the severity of the condition all factor in. Not only that, to some extent practitioner experience and preference also factors in. I personally have no experience using just Tian Ma by itself. It is unusual that a single herb will effectively treat a specific condition, but certainly not impossible.

Generally for powered concentrated herbs/formula the dosage is between 3 and 8 grams, 2-3 times per day. You should mix it with boiling water, let it cool down a bit, and drink it while still hot. I’d recommend taking it late afternoon and shortly before bed.
