This study on the genesis and evolution of a cluster of disorders (called sitapitta, i.e, urticaria and syndromes resembling it) and their treatment in Indian medical literature from early times to the present day is the first of its kind.It deals with antecedent concepts in the classical sa?hit's and the sudden appearance of a well-defined nosological entity in a later period, together with the therapeutic measures developed.The fate of this entity in a large number of medical treatises is systematically explored. Continuity and change in both theory and therapy are thus seen to be present until our own times.

Chromic acid and chromium oxide are the two versatile Cr(VI) oxidants known to organic chemists for decades. The introduction of the Core's reagent , viz: pyridinium chlorochromate, in 1975 followed by the publications on several Cr(VI) oxidizing agents containing the -onium chromates and halochromates in the last three decades have very much changed the chemistry of oxidations with Chromium VI. Several of these new reagents have been shown to be mild so that they can be handled easily and the reacton products may also be controlled. Some of them are highly selective oxidants for positions like allylic hydroxylic group, etc., and some other are highly regioselective. The information on more than 36 such reagents reported in various internationally reputed journals spanning about 280 references have been collected and provided in this book in such a manner that it will be very useful for professionals, researchers, teachers and graduate students working in organic synthesis.
