Abstract
Modern Natural Health Products (NHPs) are medicinal dosage forms also known and regulated variously as Dietary Supplements, Phytomedicines and Complementary and Alternative Medicines in different countries. Related regulated food products include Medicinal Foods, Supplemented Foods, Functional Foods, and Nutraceuticals, while cannabis products are regulated separately. All of the above are derived from or inspired by natural products that have existed for millennia. Most have been developed through ancient medical systems (e.g. Traditional Chinese Medicine and Ayurveda) and distinct indigenous cultures, which combine worldview, beliefs, practices, into “ways of knowing”. Others were identified or advanced through scientific discovery and biotechnology. Together, they have contributed—and will continue to contribute—to human health and economy at a global scale.

When water is used as the solvent at moderately high pressure and temperature, which increases the dielectric constant of water, and makes it very effective for extraction of phenolics in fruits and vegetables
Supercritical fluid extraction (SCE) using CO2 at temperatures and pressures where liquid, gas and solid co-exist is ideal for lipophilic compounds while leaving hydrophilic compounds behind
Summary
Modern Natural Health Products (NHPs) are medicinal dosage forms known and regulated variously as Dietary Supplements, Phytomedicines and Complementary and Alternative Medicines in different countries. For all areas of the world, advances in knowledge and technology coming, for example, from food and analytical sciences are helping to improve NHPs and related products and to provide evidence for their health benefits. Advancements in genomics and proteomics facilitate the elucidation and exploitation of biosynthetic pathways but the investigation of NHP effects in humans, experimental models, and in the plant (or other organism). Details of these recent developments in the field follow with emphasis on plant derived products
