Dr. Dewey discusses the homeopathy treatment of Seasickness in his bestselling book Practical Homeopathic Therapeutics….

Petroleum. [Petr]

      This is by all odds the most frequently indicated remedy in seasickness. Dr. Bayes says it is the only medicine that he found to be of any use; he used the 3d potency. Hughes also praises it in this affection and the writer has used it with success. The special symptoms are nausea, which is accompanied by vertigo, the vertigo coming on especially when the a patient raises his eyes. These symptoms are worse from motion or riding; there is rather a persistent nausea and qualmishness than vomiting, although bilious vomiting also occurs. It undoubtedly has prophylactic powers and may be taken night and morning for a week or two before sailing.

Cocculus. [Cocc]

      This is perhaps one of the oldest homoeopathic remedies in seasickness. Great nausea is one of its characteristic symptoms; it is provoked by motion, change of posture and of posture and especially from riding in a carriage, on the cars, or on a boat. This nausea is accompanied by vertigo, with a tendency to faint.

Apomorphia. [Apom]

      This remedy has gained quite a reputation for the cure of seasickness. There are no special indications for its use, except that it has vomiting of cerebral origin. It should never be given lower than the 6x potency.

**Theridion has proved useful in seasickness in nervous women; they shut their eyes to get rid of the motion of the vessel and grow deathly sick.

**Staphisagria has also attained some success in the treatment of seasickness. **Glonoine is the remedy especially when there is giddiness, warm sickening sensation in the chest and stomach and a faint feeling.

**Tabacum produces an astonishing resemblance to seasickness and car sickness and car sickness, and in the higher potencies is sometimes very efficacious.
