title: Comparison of two purification products of shankha bhasma: A prospective randomized control trial.
abstract: BACKGROUND
  Shankha bhasma is widely used in the treatment of gastroesophageal reflux disease (GERD) patients.
  
  
  OBJECTIVE
  To compare the efficacy of two purification methods of shankha bhasma in relieving GERD symptoms. In method A, purification was done with lemon juice and method B with sour gruel.
  
  
  METHODS
  Patients with heartburn since at least four days/week but who did undergo endoscopy to assess esophageal mucosa could participate. In this single-phase, single-center, prospective, randomized control trial, the patients were randomized to receive either shankha bhasma purified by method A or by method B. The primary efficacy variable was the proportion of patients with resolution of heartburn at week 4 and week 8.
  
  
  METHODS
  Single-phase, single-center, prospective, randomized control trial in a hospital setting.
  
  
  RESULTS
  Of the total 70 patients who received samples A and B in a randomized double-blind manner, 65% of the patients showed resolution of symptoms in sample A and 28% in sample B at the end of four weeks, whereas, 71% of the patients showed resolution of symptoms in sample A and 31% in sample B at the end of eight weeks; P value was statistically significant for resolution of symptoms (P <0.005).
  
  
  CONCLUSIONS
  Purification of shankha bhasma by lemon juice method is better than sour gruel method in terms of clinical outcome in GERD patients and is hence recommended.
