How to Increase Your Energy, 15th century

Getty MS Ludwig XV i, f. 13 (15th c.)

For the evil that is called lethargy. Take your own hair, burnt, mixed with vinegar and a little pitch, and lay that over the nostrils. Also, swine’s dung laid thereto is good. Also, place the eyes, the heart and the tongue of the nightingale under the pillow, or in the bed, and it shall keep him waking while he lies there, and whoever drinks it, he shall never sleep.

15th century medical compilation (British Library Sloane 3489, f. 1r-v)
