The present invention provides for a derivative of monoterpene or sesquiterpene, such as a perillyl alcohol derivative. For example, the perillyl alcohol derivative may be a perillyl alcohol carbamate. The perillyl alcohol derivative may be perillyl alcohol conjugated with a therapeutic agent such as a chemotherapeutic agent. The present invention also provides for a method of treating a disease such as cancer, comprising the step of delivering to a patient a therapeutically effective amount of a derivative of monoterpene (or sesquiterpene). The route of administration may vary, and can include, inhalation, intranasal, oral, transdermal, intravenous, subcutaneous or intramuscular injection.
