text: It is actually a homeopathic remedy, not herbal.  It is made from the venom of a viper (snake).  \n\nHomeopathic remedies use the original substance, in this case the venom, and dilute it greatly via a methed called potentization.  This is said to remove any toxic properties of the substance, but to keep in tact the healing aspects of the remedy.  The urls listed previously have some decent information, but homeopathy can be very complex and it is often better to seek professional help for homeopathic treatment.\n\nThe number and letter next to the name indicate the potency, or how diluted it is.  There are two scales, C for x100 and X for x10.
