Powdered orris-root has been used as an application to the hair, and in some
young girls has produced violent symptoms. Headache and giddiness occurred on waking in the
morning. Complete paralysis of right side. In one case convulsions and delirium, from which
complete recovery did not take place for three months. It gives an odour of violets to the breath,
and communicates to vinegar a flavour of raspberries, hence is used in manufacture of Raspberry
Vinegar.
