Homeopathy Baryta Baryta Carb. Barium Carbonate / Witherite Baryta carbonica The homeopathic remedy Baryta carb. is prepared using the chemical barium carbonate, which is also known as witherite. English botanist and geologist William Withering was the first to discover witherite way back in 1783. Therapeutically, this compound was used to treat tuberculosis as well as swellings of the glands. It may be noted that the element barium is found in the crust of the earth in other minerals like barite and witherite. When this compound is heated in the dark, it glows and currently the amalgams enclosed by witherite are being employed in radiology. In addition, witherite is also used to manufacture superior quality glassware as well as optical glass.
