  • Tom's Comment

    1. Chan Su is Toxic. It is the venomous secretion of a toad. A dangerous practice on the street is to use it to sustain penile erection. Chan Su is often referred to as \"stone\" on the street.
    2. Research in China has shown that it may be helpful in oncology cases. It is not used by a community practice practitioner.
