Sorry I didn't see this late last night -- it's only a problem if "allergic" to bees.
Do you have Benedryl? (diphenhydramine) 1-2 mg/lb body weight. Not sure which Chinese herb acts as an antihistamine, sorry. Apis is a homeopathic that would work very well if that's available.
But if Moca hasn't reacted by now it should be fine -- usually anaphylactic shock happens really fast. It can make the airway swell shut (particularly if they get stung in the mouth or throat). It can also cause a "hives" reaction (not as in 'bee hive' but as in a swollen rash breaking out on the body).
Hope Moca is ok!
