The French alchemist Petri Murien exclusively handcrafts Tonic Gold in limited quantities in his laboratory in India. He is one of the world's foremost traditional alchemists. He studied alchemy with masters in both the Eastern and Western traditions. His work of 30 years is a continuation of that of Paracelsus, the famous 16th century alchemist, and Rudolf Steiner, the 20th century founder of Anthroposophic Medicine and Waldorf Education.

Petri’s unique expertise is required to capture the universal essence that vivifies this powerful golden elixir. Tonic Gold is unequalled in quality and requires a year to prepare.
