Kali phoshate is a tissue salt that was traditionally used as a nerve tonic. It may help provide support during times of stress, study and over work. Kali phos may have a nourishing and tonic effect on the brain and nervous tissues, giving support when there is mental weakness or depression from excitement, stress, overwork or worry. It can also be used with other indicated remedies, chosen according to how the individual in question experiences and expresses their symptoms. Those who would benefit from Kali phos may include ‘fly-in fly-out’ or shift workers, those with demanding work schedules, and those living with a high degree of work stress or family dramas. It may be beneficial for jet lag and during convalescence after a long or taxing illness. A classic example of someone who would benefit from Kali phos is a fatigued student who is experiencing headaches and exhaustion.
