The Dotty Series Most of the works in this part of this series are named after the natural herbs that help with managing mental ilness. A medical paper published by Shahed University in Tehran, Iran looked at the herbs used to control mental illnesses for centuries. Their study used the Qur’an as the starting point – they succesfully identified 50 medicinal plants that were effective in controlling mental illnesses like anxiety, depression, nerve restlessness, Parkingson’s and other disorders. The scientific study of these substances once again backed up ancient knowledge. Common herbs have been effectively used for thousands of years for treating mental illness. This series pays hommage to this knowledge through the naming of some of the more useful herbs the study identified.
