How much mg/gr ginger in tea vs how grams in tea infuser

Question

When creating ginger tea from grated/small parts of ginger it is not clear to me what is the relationship between how much mg/gr are in the tea vs the grams of grated ginger used.
E.g. if using a tea infuser add 1 full teaspoon and leave in the hot water; the tea itself how much grams (or mg) of ginger is it supposed to have?

Update
To give some context, I am asking because since I had read about nutmeg's toxicity I always check the dosages of spices and herbs. So for ginger I read that there is a threshold of ~4grams for no side effects so I wanted to understand if having it as a tea and using too much grated ginger steeped in water could cause to exceed that. Other than this I don't need any exact measurement for any reason

Answer 1

There usually is no such thing as "how much grams is the tea supposed to have". Tea recipes are not precise, and it doesn't really matter how much ginger you use.

If there is some reason for you to want a very exact measurement in weight, then it is totally impractial to try to calculate it from a volume measurement. You should instead measure your ginger by weight.

The above assumes that you want to know how many grams of raw ginger you used to make the tea. If you want to know the total amount of ginger extract that you are drinking (after straining out the ginger solids from the tea), that is not something you can find out in practice. I don't doubt that there are laboratories equipped to measure it (given that a professional food chemist first defines precisely what should count as "ginger extract") but it is not doable under home conditions.
