The so-called wonder-drug "Kural" which some doctors have been prescribing as a pain-killer, has been ban¬ned by the Department of Health. After extensive clinical trials over a number of years the drug has been found to produce alarming side-effects. "Kural" which the manufacturers say that it produces almost miraculous results, is certainly very effective as a painkiller. Unfortunately the drug seems to speed up the ageing process, which leads to premature hair lost, stiffening of the joints, loss of memory and eventually, premature senile dementia.
