Many anesthetics are metabolized by the liver, so it's generally a good idea to support the liver with natural treatments, such as milk thistle and castor oil packs. These protect the liver against toxic effects of the anesthesia and enhance recovery.
For more specific symptomatic relief, such as nausea and vomiting: homeopathic ipecac, acupuncture or moxa of Pericardium 6 are often useful with nutritional IV therapy to replenish loss of fluid and nutrients.
For muscle aches: Magnesium rich Epsom salt baths or warm compresses and MSM
Furthermore, Vitamin A, C, zinc and bioflavonoids are nutrients essential for general surgery recovery.
