Found a site last night that was fairly interesting. Someone was
apparently recreating the medicine Hijikata sold to see if it really
worked or not. Unfortunately the translator refused to make clear
what the results were! Oh well... One thing of interest that did come
up was the fact that the method for making the medicine was supposed
to have been given to the family by a kappa through a dream. (Oddly
enough there are many tales in the Faery lore of Western Europe that
have people learning medicine from river-dwelling faery.)
The site is:

There was another site I glanced through that seems to have info on
the Shinsengumi's movements during various battles (like Toba-
Fushimi), but the translator didn't make enough sense of them for me
to know who was doing what or why. Perhaps someone else can make
heads or tails of it, so I'll include the link here.
