Biodiversity Hertige Library didn't turn up anything, both with 'gualtheria insipida' and 'chichaja' as search string. Maybe I overlooked something?
Their search doesn't have any spellcheck on it... it looks like you transposed the "a" and "u" in Gaultheria. Here's a link to
the search results. The ones that I read were mostly botanical descriptions with minimal commentary... but it would probably be worthwhile to check all of them just in case.
I also found
this site with a google search for chichaja + Gaultheria. It mentions that
Gaultheria insipida is used to treat chronic pain, but no further details beyond that.
As far as the chemistry of the plant goes, it looks like it's only been studied for chemotaxonomic purposes. That study looks at flavonoids, so it may or may not be relevant to the psychoactive properties of the plant -- see nen888's
Passifloras of Interest..(& MAOI plant Flavonoids) for some discussion of potential flavonoid psychoactivity. Still, your best bet is probably to look at closely-related species and see if any of them have been chemically studied.
Gaultheria is a pretty diverse genus (it includes things like wintergreen and salal), so to figure out which species are most closely related, you should check out the phylogenetic studies that include
G. insipida alluded to in my earlier post.
Also there's
this library record for a book. It seems to indicate that "chichaja" can also refer to
Gaultheria glomerata... so that species might be worth looking into as well.
Soon the ICPR lectures will come online and I can post a link, so you can all hear the stuff that triggered me to find out more.
Looking forward to it... sounds intriguing!
