We use low-temperature and relatively low-pressure CO2 extractions for our products. Ethanol, the most historically used method for hemp extracts, is also used for our isolate products.
Bluebird Botanicals does not use petroleum or toxic chemicals for our solvent extractions. Some manufacturers may use butane or other chemicals to separate the plant matter and medicinal chemicals, but we opt for the more natural route. The carbon dioxide or alcohol used to create our full-plant hemp extracts is almost fully evaporated away to leave behind a pure hemp extract oil containing a wide variety of nutritious compounds, including amino acids, vitamins, omega fatty acids, trace minerals, terpenes, and more. There may occasionally be trace amounts of ethanol present in products, but it never exceeds the safety guidelines set forth by California’s Proposition 65.
Our isolate products undergo a further process of winterization, which uses solvents and cold temperatures to remove lipids, waxes, chlorophyll, and terpenes which create the signature taste and smell of hemp. It also makes the product more concentrated. We've got something for everyone.
