It is a leading homeopathic medicine for managing cases of increased sexual desire, mania of obscene (related to sexual matter) nature, muscle twitchings, jerking, etc.

Scope As A Homeopathic Remedy

1. Action On Mind And Brain (Lasciviousness, Nymphomania, Sexual Mania, Mania, Delirium, Schizophrenia, Alcoholism, Alzheimer’s Disease)

The most prominent and broad action of Hyoscyamus Niger is seen on the mind and brain. It can effectively manage various complaints related to mind and brain. Among these the leading feature that guides its use is lasciviousness which is a strong desire for sex. Those needing this medicine talk excessively about sex-related topics or sing amorous songs that express desire for sexual activity. They tend to fondle genitals, may take off clothes and expose genitals. It is the best homeopathic medicine for nymphomania (increased sexual desire in women).

Hyoscyamus Niger is well-known for treating cases of schizophrenia (a mental health condition affecting thinking, emotions, and behavior). Different kind of hallucinations occur like seeing or hearing things that do not exist, or delusions (fixed, false beliefs not based on reality). Those needing it suffer from some specific types of delusions, like delusion of being poisoned, being sold or being bitten, being stalked, etc. There is marked suspiciousness in them. They may be particularly suspicious of a plot being made to harm them. Another alarming symptom is talking with imaginary or dead people.

Another main indication for administering Hyoscyamus Niger is delirium (sudden change in brain leading to confused thinking and emotional disturbance). It can be given in cases of muttering delirium in which the sufferer’s speech is not understandable. There is decreased response to environmental stimuli and carphologia (lint picking of clothes or bed linen). Along with delirium, weakness is also marked. Hyoscyamus Niger is also well indicated for delirium when attended with restlessness with sudden jumping out of bed, moving from one place to another, constant talking, jerking of limbs, wild staring look. Use of this medicine can also be thought of in cases of delirium tremors that occurs in people who are trying to quit alcohol. The guiding features to use it here are delirium with aversion to light, constant talking, trembling of whole body and sensation as if a snake is wriggling towards the sufferer. Along with this, there is desire to escape, loss of appetite and sleeplessness.

Further it is an important medicine for managing mania when there is urge to bite, strike, quarrel, scold, kill and tear clothes. It is also best suited for cases of erotomania (the sufferer believes that someone is in love with him/her when there is no such thing). There may be a tendency to expose genitals.

This medicine is suitable for getting rid of certain fears. These include fear of being poisoned, being alone, water (hydrophobia), and syphilophobia (fear of being infected with syphilis i.e. a sexually transmitted infection caused by bacteria treponema pallidum).

Cases of Alzheimer’s disease (brain disorder where the death of brain cells occurs that leads to memory loss and gradually destroys thinking, behaviour and social skills) can also be well managed with this medicine.

Besides, Hyoscyamus Niger is a valuable medicine for cases of convulsions (fits). Here, it is given when there is clenching of fist during fits. Before convulsions, vertigo occurs, and the fit ends in deep sleep. It is a top-listed medicine for convulsions in children that occurs from fright.

Lastly, it is well-indicated for managing cases of alcoholism and drug addiction.
