I looked up the green fruit, cempoka and I think it is this: http://en.wikipedia.org/wiki/Michelia_champaca. Does that look right floatergasted?

I expect it would be possible to get a distilled version of whatever is in it.

I found this information about it:
In traditional medicine, an infusion or decoction of flowers is given in dyspepsia, nausea and fevers; also for preventing scalding in renal disease. Flowers, macerated in oil, are applied externally in cephalalgia, opthalmia, nasal infections, sinus, rheumatism, gout and vertigo. While yellow colored flower also use for high fever by boiling the flower.

It also use as anti inflammatory and antipyretic. Juice leaves is given with honey in colic. Leaves are also applied in andolent swellings.
