Ephedrine is a member of the adrenergic bronchodilator class of drugs that serve to open up the bronchial tubes of the lungs. These drugs are used to treat the symptoms of asthma, chronic bronchitis, emphysema, and other lung diseases as well as to relieve coughs, wheezing and clogged breathing tubes. Ephedrine is marketed under a variety of trade names in the United States and is also used in combination with other drugs in many non-prescription medications. Side effects include dizziness, bluish coloration of the skin, skin rash, itching, and swelling. When recrystallized from the melt, ephedrine will slowly crystallize, forming beautiful sheets of dendritic needle-like crystals. The time-lapse movie was made using a modified version of the Intel Play QX3 microscope equipped for polarized light illumination with a full-wave (first order) retardation plate.
