Thread: Aqueous extract Question

What is the equivalent of a 200 mg dosage of a specific herbal aqueous extract? Is it simply 200mg of the dried herb dissolved in water and concentrated? I'm trying to determine how much of a dried herb I require to produce a specific volume of aqueous extract for a health product
Thanks!

It seems more likely to me that it's 200mg of the solute (the bit that gets dissolved). The way you'd weigh this is by [boiling?] the herb in water for a suitable length of time, then seiving the remaining herb out and boiling away all the water to leave the powdered solute behind. What is the herb in question?

Thanks for your reply.....The herb/spice is saffron.... The product will be in liquid form and I would like to match the equivalent dosage of 200mg of aqueous extract used in a study, so I'm trying to determine how much saffron I will require to equal that dosage of aqueous extract

I'm afraid I can't think of any way to weigh the extract without first isolating it, sorry.
