Which remedy is associated with a right-sided acute migraine worse from light and noise and is relieved by vomiting or sleep?

• A. Nux vomica
• B. Sanguinaria
• C. Sepia
• D. Spigelia

Answer: (B)

A migraine pattern that is right-sided, acutely throbbing, and made worse by light and noise fits Sanguinaria well. This remedy is classically chosen for unilateral headaches that originate on the right side and are accompanied by marked sensitivity to light (photophobia) and sound (phonophobia). The headache is often associated with nausea and may be relieved by vomiting, and sleep can also bring relief. These modalities—right-sided location, aggravation from bright light and noise, and relief from vomiting or sleep—together form a signature picture for Sanguinaria.

In contrast, Spigelia tends to produce more neuralgic, sharp pains that are often left-sided and less characteristically relieved by vomiting. Nux vomica headaches are commonly tied to mental overwork, digestive upset, or substance excesses and don’t fit the classic right-sided, light-and-noise–provoked pattern with vomiting relief. Sepia headaches are more linked to hormonal factors and different time patterns or accompanying symptoms.
