First time tincturer

hello all

I am still faithfully taking the bf&c and herbal calcium tinctures i order from Unyquity but would love now to make my own. My problem is knowing where to start. I have read many posts on here about tincturing methods but am still unsure about several things so i hope you don't mind enlightening me please.
First, for the bf&c can i use the tea mix and just add alcohol or should i tincture each herb separately and if so what quantities of the separate, single herb tinctures do i mix together to ultimately make the bf@c tincture?
Secondly, I think i can only get hold of dried herbs would this be much less effective?
Also does anyone know the ratios of herbs needed to make the herbal calcium tincture?
Finally i have a significant bit of damage to bone and cartilage and think i need to up my doses considerably but can taking high doses be dangerous e.g would more than 40 dropperful x4 a day be safe?

P.s whilst here i'd just like to personally thank Uny for all her support and wisdom

best wishes to everyone
