Dried Hibiscus Serving Size

Hello everyone, I am trying to determine the correct serving size for dried hibiscus flowers that my facility repacks (in the U.S). I have looked at the FDA's RACC guide and am unsure what category this product would fall under. Does anyone have experience with edible flowers who could point me in the right direction? Thank you in advance!

How are the dried hibiscus flowers used or consumed by the end user?  This can help narrow down the category.

botanticals, herbs - depending on use

Based on the guide, it looks like you have 2 options:

Spices, herbs (other than dietary supplements) 1/4 tsp or 0.5 g if not measurable by teaspoon 1/4 tsp (_ g); _ piece(s) (_ g) if not measurable by teaspoons (e.g., bay leaf) All spices and herbs (except those that contain salt) used to flavor food (e.g., granulated garlic, granulated onion, garlic powder, onion powder, thyme leaves); seeds used as spices (e.g., poppy seed, sesame seed, celery seed). 

OR

Drink mixes (without alcohol): All other types (e.g., flavored syrups and powdered drink mixes) Amount to make 360 mL drink (without ice) _ fl oz ( _ mL); _ tsp (_ g); _ tbsp (_ g) Mixers for alcoholic beverages (e.g., pina-colada drink mixers); flavored or sweetened drink mixers and drink mixers used to make mixed drinks (e.g., ice tea drink mixes); flavored or sweetened syrups or powder drink mixes without alcohol (e.g., hazelnut flavoring syrup).

This is the most common dried hibiscus recipe I know:

I picked that site specifically because it contains serving information that would allow you to break down a single serving.

1 cup dried hibiscus=2L /360mL per FDA serving.... I'm sure that you can weigh that to get a gram estimate. 

Hope that helps.
