Although there was not necessarily a cure for the disease there was a cure for the symptoms. Headaches were relieved by rose, lavender, sage and bay. Sickness or nausea was treated with wormwood, mint, and balm. Lung problems were treated with liquorice and comfrey. Vinegar was used as a cleansing agent as it was believed that it would kill disease. But bloodletting was commonly thought to be one of the best ways to treat the plague. Black Death was treated by lancing the painful swellings and applying a warm poultice of butter, onion and garlic. Various other remedies were tried including arsenic, lily root and even dried toad. Wouldn't it be strange if the next time you had a headahe you went to the doctors and they gave you lavender to eat? During later outbreaks of plague people experimented with using tobacco to help cure the disease.
