Reputation and efficacy 'Warburg's Tincture' was a well-known drug in the Victorian era. It earned itself a well regarded international reputation in certain quarters of the medical profession, many attesting to its efficacy and value. One of the most notable and strongest advocates of Warburg's Tincture was Surgeon-General W. C. Maclean, C.B, (1811–1898), Professor of Military Medicine at the Army Medical School, at Chatham and later at the Royal Victoria Military Hospital, Netley, from 1860 until 1885. Maclean contributed the chapters on malarial fevers and dysentery in A System of Medicine, edited by Sir John Russell Reynolds (the latter being "an eminent and highly influential physician in the Victorian era who held the Presidencies of the Royal College of Physicians of London, and of the British Medical Association"). Maclean considered Warburg's Tincture to be the best drug for the treatment of malaria and, in his lectures and writings on tropical diseases, he strongly recommended its use. In addition to Surgeon-General Maclean, Warburg's Tincture was highly praised by many other eminent medical professionals of the Victorian era, including: Sir James Johnson M.D. - physician extraordinary to King William IV. Sir James Clark M.D. - royal physician to Queen Victoria and Prince Albert. Sir William Henry Broadbent, 1st Baronet, M.D. - St Mary's Hospital, London and London Fever Hospital, Physician in Ordinary to Queen Victoria and King Edward VII. ("Warburg’s Tincture has long held a high reputation in India, as a remedy of undoubted and indeed unequalled power in the treatment of the malignant malarial fevers of that country and of cholera. Testimony to its efficacy has come from men whose capability and opportunities of forming an opinion could not be disputed", 1877) Dr Thomas Southwood Smith - London Fever Hospital, and recognised expert on the treatment of fevers. Dr Benjamin Guy Babington - Guy's Hospital ("I consider it the most potent anti-intermittent medicine I have ever employed", 1851). Dr F. C.
