Browsing Shakespeare’s London on 5 Groats a Day by Richard Tames the other day I came across the following remedies.

Loss of hair. Try doves’ dung, burnt, failing that the ashes of a small frog

Nits in the hair. Comb with mercury ointment and pig fat
Yep that should see off the nits, if it doesn’t see you off first

Head colds. A sliver of turnip in the nostril

Tinnitus. Oil of hempseed in the afflicted ear, followed by hopping on that side

Retention of urine. Three large lice inserted in the penis
Hmm, I can imagine that might work too; not sure I fancy the side effects though

Asthma. The lungs of a fox washed in wine, herb and liquorice
OMG

Tuberculosis. Incurable, but for relief try asses’ milk and snails in their shells

I think on balance I’m glad I live in the 21st century!
