The market for homeopathic and herbal remedies grew 17% between 2005 and 2009, reaching $5.9 billion, and is expected to continue steady growth of 3.5% annually through 2015. Homeopathic medicines use minute doses of plants or minerals to address symptoms, and are regulated by the FDA as drugs rather than supplements. The Peerless Double-Arm Sigma Mixer is preferred by homeopathic product manufacturers as it can produce consistent output while meeting high sanitation requirements, with its ability to thoroughly blend products in each batch regardless of consistency.
