Is nux vomica safe to use for post-op nausea/vomitting after orthopedic surgery? have not had good luck with other anti-emetics.

I wouldn't. : Nux vomica is the extract from the strychnine tree and is a deadly poison if ingested in sufficient dose. Before i experimented with that, i'd talk to your surgeon about your nausea. He may be able to change your pain medication, reducing narcotics which cause nausea and adding antiinflammatories for better analgesia.

Homeopathic: Homeopathic nux vomica is very safe, and depending on your specific symptoms could be very effective. My colleague is correct that it's prepared from a poisonous substance containing strychnine -- but the manufacturing process dilutes this while retaining the healing properties. Homeopathic remedies interact with your healing system, an energetic aspect of you with wide-reaching effects.
