Yes! sure
Salicicum Acidicum and Silicea (SiO2) are two different things. Silicea is not written in German Pharmacopeia. They can not prepare Silicea as a rule. But Salicium Acid is written in German Pharmacopeia. The starting materia of Silicea is Acid Salicium which is an acid but silicea is not an acid. So technically speaking silicea is not salicicum acidicum. I don't know what the actual compound is in Silicea potency. This can only be verified by experiment. Which is not available in homeopathy :razz:
These kind of examples are giving bad name to homeopathy. Which encourage people to say "Homeopathy is a fraud". The reason is you can't testify what you are saying. O.K
