Drug info - Kali Phos. 30X

[Nahbus]

SWIM just bought a little vial of 100 pills from a health food store labelled "Kali Phos. 30X". He was interested in the effects listed, but can't really find much info on it.

The vial reads:
"Helps restore mental alertness or wakefulness when experiencing fatigue or drowsiness. Also for relief of occasional sleeplessness.
Characteristics: You may feel weak and tired caused by worry, excitement or overwork. You may feel anxious, nervous or irritable."

Are the "characteristics" side effects, or the symptoms one would have in order to take this?

Anymore info on this would be great. SWIM really just wants to know if its worth his while to take. Is it better than ephedrine? Please, SWIM needs information!
Thanks.
