Stomach aches can be causes by a variety of disease processes. In our local context in Southeast Asia, the most common causes of stomach aches include gastroenteritis, gastritis and constipation. Dangerous causes of stomach aches can include appendicitis or a perforated organ in the abdomen or pelvis. 

Certain medicated oils may relieve stomach ache as a symptom. However, it will not resolve the underlying issue which is more important. If the stomach aches are severe, persistent or excessively frequent, it is advisable to visit a medical practitioner for a proper assessment and recommendations on the next steps of action.
