    Botanical Source.—This plant is a perennial,   herbaceous, dull-green plant, armed with minute rigid hairs or prickles, which   transmit a venomous fluid when pressed. The stem is obtusely 4-angled,   branching, 2 to 4 feet high, arising from a creeping and branching root, with   fleshy shoots and many fibers. The leaves are opposite, petiolate, cordate,   lance-ovate, spreading, conspicuously acuminate, coarsely and acutely serrate,   the point entire, armed with stings, and are 3 or 4 inches long, and about half   as wide. 
   
  
    
      The flowers are small, green, monoecious or dioecious, in branching,   clustered, axillary, interrupted spikes, longer than the petioles.
      This is a well-known plant, common to Europe and the United States, growing in   waste places, by woodsides, in hedges, and in gardens, flowering from June to   September. A decoction of the plant, strongly salted, will quickly coagulate   milk without imparting to it any unpleasant flavor. The leaves and root are   generally used, and yield their virtues to water. 
      A fabric, known as   nettle-cloth, has been woven from the bast fibers of nettle. The young shoots   have been boiled and eaten as a remedy for scurvy. The irritation caused by   rubbing the sharp hairs of the nettle on the skin, is believed to be caused by   the free formic acid which they contain.
