C4 Healthlabs is dedicated to producing pure, organic and safe CBD oil. In efforts to create products that live up to our demands, we test the soils in which our hemp is grown, continually monitor our harvests, and always test our extracts. From soil to seed, oil and ingredients, our products deliver organic, contaminant-free and true-to-label ingredients. Our quality and consistency are the result of our methodology.


The Farm

C4 Healthlabs Hemp Farm in Tennessee

Our CBD oils are made from a Tennessee–grown certified cultivar of Italian fiber hemp, naturally rich in CBD. This variety of hemp responds well to the weather conditions of Tennessee. Grown exclusively on pastureland once grazed by free-range cattle, the soil retains its biological activity, producing truly superior hemp flowers. Our growers believe that any hemp crop grown for consumption by people or animals should be grown without the use of insecticides, herbicides or micro-biocides. Our hemp crops are nourished with the goodness of organic fertilizers and lactose probiotics (raw milk). This dedication to organic farming improves both the quality of our crops and the soil in which its grown. This ideal combination of sun, soil and organic fertilizer results in seedless hemp flowers of superb quality.

Each day our growers inspect the hemp trichomes with a microscope to gauge their maturation. Our seedless hemp flowers are harvested by hand when they have reached peak maturity. Once harvested, it’s time for our growers to cure and process. Instead of quick-drying, our growers choose to cure the flowers. This method of slow drying increases potency preserves terpenes — the aromatic compounds that give hemp its unique smell and complex flavor — and allows our cured hemp to be stored for longer periods without concern for mold or the loss of cannabinoid content. After the curing process is complete, these seedless buds are quickly stored in airtight containers at a controlled temperature.

Next is the extraction process. Our team investigated several methods, including Butane, CO2, and Ethanol — all extraction methods used in the industry today in the production of hemp. Butane is the most common extraction method for many reasons but is highly combustible, making it a dangerous method of extraction. Furthermore, butane can be an unfavorable method due to the availability of low cost, low-quality butane that can retain an array of toxins that are harmful to humans. CO2, although safer, has a lengthy purification process, which can take away from the final cannabinoid and terpenoid profile of CBD extracts yielded during CO2 extraction. After several months of testing, our team settled on a two-step process that combines the use of organic Ethanol — because of its effectiveness, efficiency, and safety — and the use of MCT oil, a derivative of coconut oil, and the most bio-available form of energy. This 36-hour proprietary two-step extraction and distillation process produces a superior and safe CBD oil that tastes great and works remarkably well.

After extraction our CBD oils go through an additional 18-hour short-path distillation processThis results in CBD oils that are over 99% pure and are the cleanest, clearest, and by far one of the most potent CBD concentrates available on the market. Double-distillation produces pure cannabinoid oils that contain little to no residual hemp flavor or aroma, so they’re virtually tasteless and odorless. We are not aware of another CBD oil brand going through the added time and expense of double distillation. 

Although our labs test every batch of our CBD oil for purity and CBD potency, we send every batch of our full-spectrum CBD oil to a 3rd party lab for testing, and receive a certificate of analysis (COA) that documents our cannabinoid concentrations and confirms safe CBD oils. Please visit our contact page to request a copy of our most recent certificate of analysis.
