Nux vomica is chiefly linked to workaholic personalities who drive themselves to stress and excess. Ambitious and pushy, they thrive on challenges, and often work in entrepreneurial or managerial jobs. The typical pattern is of someone who is oversensitive and intolerant of criticism, yet perfectionist and often very critical of others. Such highly driven people tend to overload their bodies at play as well as at work. They tend to have high sex drives, consume too much rich food, coffee, and alcohol, and abuse drugs. This indulgence can create tension and sleeplessness, and often leads to digestive disorders (most seriously, peptic ulcers, irritable bowel syndrome, or liver problems when the body can no longer keep up with the lifestyle).
If the profile matches, Nux vomica is given for irritability, insomnia, digestive symptoms, colds and influenza, asthma, cystitis, and menstrual or pregnancy problems. Typically symptoms are worse for cold, noise, light, and odors.

Poison-nut
Is the greatest of polychrests, because the bulk of its symptoms correspond in similarity with those of the commonest and most frequent of diseases. It is frequently the first remedy, indicated after much dosing, establishing a sort of equilibrium of forces and counteracting chronic effects.
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. Since these frailties are more yielded to by men than women. Nux is pre-eminently a male remedy. These conditions, produce an irritable, nervous system, hypersensitive and over-impressionable, which Nux will do much to soothe and calm. Especially adapted to digestive disturbances, portal congestion, and hypochondrical states depending thereon. Convulsions, with consciousness; worse, touch, moving. Zealous fiery temperament. Nux patients are easily chilled, avoid open air, etc. Nux always seems to be out of tune; inharmonious spasmodic action.

Antidote
Everywhere in this remedy we observe the striking oversensitiveness of the patient; it is brought out in all the symptoms.
Irritable; oversensitive to noise, to light, to the least current of air, to his surroundings; extremely touchy in regard to his food; many kinds of food disturb, strong foods disturb; he is aggravated by meat; craves stimulants, pungent, bitter, succulent things, something to brace him up.
Oversensitive to medicines. One reason why there are so many Nux patients is because people have been overdrugged by the old school. When a patient comes from the old school and had prescribing, having had stimulants and tonics to brace him up, wine and stimulants of all sorts, it is sometimes impossible to get reliable symptoms, to get the patient settled down, until we give Nux as an antidote.
