Nux is pre-eminently the remedy for many of the conditions incident to modern life. The typical Nux patient is rather thin, spare, quick, active, nervous, and irritable. He does a good deal of mental work; has mental strains and leads a sedentary life, found in prolonged office work, overstudy, and close application to business, with its cares and anxieties. This indoor life and mental strain seeks stimulants, coffee, wine, possibly in excess; or, again, he hopes to quiet his excitement, by indulging in the sedative effects of tobacco, if not really a victim, to the seductive drugs, like opium, etc. These things are associated with other indulgences; at table, he takes preferably rich and stimulating food; wine and women play their part to make him forget the close application of the day. Late hours are a consequence; a thick head, dyspepsia, and irritable temper are the next day's inheritance. Now he takes some cathartic, liver pills, or mineral water, and soon gets into the habit of taking these things, which still further complicate matters.
