Qing Dai - Indigo Concentrated Granules 100g Treasure of East

Q: Does this tea stain your teeth blue?

It could potentially stain your teeth purple with enough of it consumed as tea, but If you are taking it for health I don't see why you would mix it with water. Dosage is roughly 1 gram per dose. I just put the small amount of powder on my tongue and swallow... doesn't even touch my teeth.

Q: How much of a tsp is a gram?

The product I ordered came in today and it’s a powder form, not a capsule. 1/4 teaspoon is 1.42 grams though, so you can go from there to increase or decrease your dosage
