Well, for one herbs really shouldn't be used until the age of 21 because your body still has the chance to produce its own hormones which are much more potent than those found in plants. The massages that you have mentioned will help stimulate your body's natural hormone production. If you look through the massage section there is a post about Japanese massage which has a link to a great video. The Japanese technique pinpoints cert accupressure points to stimulate further hormone production. So, in short, you may not be experiencing growth because the herb could be blocking receptors your body was using for its own hormones causing weaker effects.

My two cents: stick to massage and if in four years you're not happy with your size, look into them again.
