English lavender

English lavender; Lavendula officinalis

Lavare is the Latin verb "to wash". The Romans used the fragrance of the blossoms in their bath water hence the origin of the name lavendula. In the Middle Ages, it was used alone or in combination with other herbs to treat insomnia, anxiety states, migraine headaches and depression. The fragrance is relaxing hence the dry blossoms were stuffed in pillows and given to agitated patients to produce sedation. The oil is strongly antiseptic and used to heal wounds. 

It is native to the Mediterranean (Spain, France, Italy, Croatia etc.).
