Phosphoricum acidum
Phosphoric acid · Phosphoric acid, glacial phosphoric acid, orthophosphoric acid. · Mineral
Phosphoric ac. is especially suited to mild, calm, gentle people who tend to be sensitive and emotionally dependent on others. When in good health, they are usually strong, but their constitutions are easily undermined by debilitating illness, emotional trauma, homesickness, or repeated drug abuse, leading to severe exhaustion.
Profuse perspiration and chilliness are typical symptoms, as are loss of appetite and a craving for refreshing drinks and juicy fruits. The remedy is used for acute grief or stress, severe exhaustion, diarrhea, and headaches. It is also given for childhood growing pains and insomnia or exam nerves.

- cravings for fruits and juicy foods

Phosphoric Acid
The common acid "debility" is very marked in this remedy, producing a nervous exhaustion. Mental debility first; later physical. A congenial soil for the action of Phos acid is found in young people who grow rapidly, and who are overtaxed, mentally or physically. Whenever the system has been exposed to the ravages of acute disease, excesses, grief, loss of vital fluids, we obtain conditions calling for it.

Mind
"Mental enfeeblement" is the thought that will come into the mind when considering what the Phosphoric acid patient says, does and looks.
The mind seems tired. When questioned he answers slowly or does not speak, but only looks at the questioner. He is too tired to talk or even think. He says:
"Don't talk to me; let me alone."
This state is found in both acute and chronic diseases. He is so tired in mind, perfectly exhausted.
In chronic diseases when brought on from long study; prolonged worry in business men; in feeble school girls, when become relaxed from very little effort. In acute diseases he, especially in typhoid fever, is averse to speaking or answering questions. He merely looks. Finally he rouses up and says:
