Formic acid : A multicentric observational homoeopathic clinical verification trial

Aims: This study was done to clinically verify the symptomatology of Formic acid by ascertaining the symptoms improved during verification and to incorporate new findings (if any) to the known symptomatology of Formic acid . Methods: A multicentric observational clinical verification study was conducted at nine research centers of Central Council for Research in Homoeopathy to verify the proving symptoms of rarely used medicine, Formic acid . Two hundred and seventy participants having symptomatological similarity with Formic acid were included and prescribed in 6C, 30C, 200C, and 1M potencies, as per need of each case. The data were compiled in a specially designed Excel spreadsheet for further analysis. The collected data were presented in terms of descriptive statistics. Prevalence of the symptoms in the responding and nonresponding population was compared using Chi-square or Fisheru0027s exact test. Results: Out of 266 followed up patients, 215 cases responded (80.8%) with 95% confidence interval of 0.75-0.85. The number of symptoms verified was as follows: proving symptoms ( n = 11) and new observations ( n = 22). The widely emerged new general symptoms, i.e., clean tongue, disturbed sleep, loose stool, tastelessness, and profuse sweat may be worth consideration during prescription of Formic acid. Conclusions: The proving symptoms of Formic acid could be verified clinically, but the correlation of patient-specific symptom needs cautious interpretation. Further replication on larger sample and estimation of likelihood ratio in real-time clinical practice are needed.
