This preparation is recommended by the vendor—
“for the positive and speedy cure of epilepsy or fits, dyspepsia, indigestion, all derangements of the stomach and bowels, and for every form of debility, no matter from what source it may arise. An unequalled tonic and nervine.”
The formula ascertained by analysis was:
| Decoction of Vervain (2 oz. to a pint) | 4 | fluid | drachms. |
| Port wine | 1 | ” | ” |
| Rectified spirit | 2 | ” | ” |
| Water to 1 fluid ounce. | |||
The dose was stated to be one dessertspoonful three times a day before eating.
