If you choose sesame oil, look for cold-pressed, chemical-free organic sesame oil for the best results from your massage therapy. To cure or purify the sesame oil, heat the oil to 212 degrees Fahrenheit. Remove from heat once this temperature is reached, cool and store for use as needed. Up to a quart of oil can be cured at a time. Of course, you should observe safety precautions when curing oil. All oils are highly flammable. Use low heat, and don't leave the oil on heat unattended. You can look for professionally cured sesame oil at stores that sell Ayurvedic products if you'd rather not do the curing yourself.
