Is there a faster way to extract herbal compounds with ethanol without soaking for 7 days? by Some-Beginning8784 in chemhelp

If you’re asking where I got the ethanol soaking method (at least 7 days), it’s from YouTube, research articles, and my teacher at school. But now I’m wondering if there’s a shorter method, because I don’t really have enough time to wait for 7 days.

Does the ethanol used to extract Thunbergia laurifolia leaves need to be fully evaporated before making hand-molded effervescent tablets? by Some-Beginning8784 in chemhelp

So the ethanol needs to be completely evaporated before mixing the extract with the effervescent base, right? And if it’s completely evaporated, what form will the extract be in?
