Potassium permanganate, however, does not have FDA approved uses and therefore non medical grade potassium permanganate is sometimes used for medical use. [citation needed] It is available under a number of brand names including Permasol, Koi Med Tricho-Ex, and Kalii permanganas RFF. [21] It is occasionally called "Condy's crystals". [15]

Henry Bollmann Condy (8 July 1826 – 24 September 1907) [1] was an English chemist and industrialist best noted for giving his name to the popular 19th and 20th century disinfectants Condy's Crystals and Condy's Fluid. Condy was born in London. [2] His mother inherited a chemical factory in Battersea from a Hungarian chemist named Dr Bollmann.
Crystal healing is a pseudoscientific alternative-medicine practice that uses semiprecious stones and crystals such as quartz, agate, amethyst or opal. Despite the common use of the term "crystal", many popular stones used in crystal healing, such as obsidian, are not technically crystals. Adherents of the practice claim that these have healing ...

The resolution of liquid crystal sensors is in the 0.1 °C (0.2 °F) range. Disposable liquid crystal thermometers have been developed for home and medical use. For example if the thermometer is put onto someone's forehead, it will change colour depending on the temperature of the person's body. There are two stages in the liquid crystals:
Crystals used in X-ray crystallography may be smaller than a millimeter across. Although crystallography can be used to characterize the disorder in an impure or irregular crystal, crystallography generally requires a pure crystal of high regularity to solve the structure of a complicated arrangement of atoms.
Liquid crystals used in dyes and inks often come microencapsulated, in the form of suspension. Liquid crystals are used in applications where the color change has to be accurately defined. They find applications in thermometers for room, refrigerator, aquarium, and medical use, and in indicators of level of propane in tanks.
