NO! Diabetic wounds are a SERIOUS issue that need serious care.  These wounds need to be seen by a doctor who is well trained in how to heal these wounds and how to handle the complications of diabetes.   Dr. Saera Arain at our office, specializes in wound care and diabetic foot care.  Do not try Dr Scholl's inserts or rubbing an essential oil on your wound.  Your sore is a complex problem that needs a complex plan of care, including methods to take the pressure off, optimizing your nutrition, checking your vascular status, and monitoring you closely for infection.  Most importantly the faster you get it healed, the less risk of losing part of your foot.
