Hi,
Many times we hear people saying that I had xyz symptom, I took so and so remedy and it went away....
Now, every individual is unique and just because they had success with a certain symptom with a certain remedy doesn't mean that that remedy will help others for the same symptom as well.
There are many remedies that cover the symptoms of anxiety, sadness, depression etc., but there is a whole lot going on with the individuals other than that particular symptom. In fact, for a remedy to properly heal, one should match the complete symptom complex (mental, emotional, physical) of the remedy to that of the patient. This is what a knowledgeable health care professional does (especially a homeopath or a naturopath).
Self medicating (yes, even with seeming harmless herbal remedies) can sometimes knock a symptom out, but leave the whole organism still unhealthy.
Thanks,
AeB
