Capillus puero qui primum decisus est podagrae impetus dicitur levare circumligatus, et in totum impubium impositus. virorum quoque capillus canis morsibus medetur ex aceto et capitum volneribus ex oleo aut vino; si credimus, a revulso cruci quartanis, combustus utique capillus carcinomati. pueri qui primus ceciderit dens, ut terram non attingat, inclusus in armillam et adsidue in bracchio habitus muliebrium locorum dolores prohibet.
(Pliny the Elder, Nat. Hist. 28.41)
The hair cut off first from a child’s head, if tied round the affected part, is said to relieve attacks of gout, as does the application of the hair of all, generally speaking, who have not arrived at puberty. The hair of adult men also, applied with vinegar, is good for dog bites, with oil or wine for wounds on the head. If we believe it, the hair of a man torn from the cross is good for quartan ague; burnt hair is certainly good for carcinoma. The first tooth of a child to fall out, provided that it does not touch the ground, if set in a bracelet and worn constantly on a woman’s arm, keeps pain away from her private parts. (tr. William Henry Samuel Jones)
