“Bicarbonate of Sodium” (Baking Soda)… “is largely used as an antacid in gastric fermentation and in sick headaches arising from this condition.” Dissolve one teaspoonful of Bicarbonate of Soda in a glass of cold water and drink.
Note: A "sick headache" is a term for a headache accompanied by nausea and vomiting, often used as a nontechnical name for a bad migraine. While it can be a general term, it's most commonly associated with severe, throbbing headaches that may include other symptoms like sensitivity to light and sound, and sometimes vomiting.
