ETST and DV Biologics Begin Testing ETST CBD (Cannabidiol) Rich Hemp Oil In Vitro on Various Human Primary Cells to See if it Serves as a Neuroprotectant Which May Help With Neurodegenerative Disorders Such as Alzheimer's and Parkinson's Disease

BOCA RATON, FL--(Marketwired - April 13, 2015) - Earth Science Tech, Inc. (ETST) ("ETST" or "the Company"), a unique biotechnology company focused on nutraceuticals, bioceuticals and dietary supplements, announced today that DV Biologics, a leading biological company, has begun third party testing on ETST High Grade CBD (Cannabidiol) Rich Hemp Oil in vitro on various human primary cells. DV Biologics has identified it will be testing if ETST High Grade CBD (Cannabidiol) Rich Hemp Oil serves as a neuroprotectant which may help with neurodegenerative disorders such as Alzheimer's and Parkinson's disease.

In order to assure the world that ETST produces the best products with scientific support, ETST has engaged the expertise of a leading independent biological company, DV Biologics LLC, to test ETST High Grade CBD (Cannabidiol) Rich Hemp Oil in vitro on various human primary cells. Using human primary cells will give ETST a better scientific understanding of what ETST High Grade CBD (Cannabidiol) Rich Hemp Oil is most beneficial for. To commence, DV Biologics has specified it will be testing if ETST High Grade CBD (Cannabidiol) Rich Hemp Oil serves as a neuroprotectant which may help with neurodegenerative disorders such as Alzheimer's and Parkinson's disease. Specifically, ETST with the help of DV Biologics will look at the role of its CBD Hemp Oil and reactive oxygen species in the brain.

"We are excited to work with DV Biologics as they have many human cell based models that can demonstrate what our High Grade CBD (Cannabidiol) Rich Hemp Oil does to different cell types in our body. We want the public to know that we are focused on providing the best CBD with scientific studies that validate our products use," stated Dr. Harvey Katz, CEO of ETST.

"We are excited to work with ETST CBD (Cannabidiol) Rich Hemp Oil. There are many therapeutic purposes for this oil and we look forward to studying the characteristics of CBD in vitro with our human primary cell models which more closely resemble the human condition," stated Dr Rafael Gonzalez, VP of Research & Development for DV Biologics. 

ETST would like to let the market know the key advantage of in vitro work is that it simplifies the system under study, so that the investigator can focus on a small number of components. Another advantage of in vitro procedures is that human cells can be used directly therefore no translation from animal to human is needed in that circumstance. In vitro testing is also rather useful in the characterization of some precise metabolism, distribution, adsorption and excretion processes taking place inside the living organism. However, further experiments, particularly in vivo studies, will be needed to determine the ultimate effects of CBD Rich Hemp Oil serving as a neuroprotectant.

ETST High Grade CBD (Cannabidiol) Rich Hemp Oil: ETST High Grade CBD (Cannabidiol) Rich Hemp Oil is all-natural, organic and formulated using a wide array of cutting-edge technologies. ETST is capable of supplying and offering its High Grade CBD Rich Hemp Oil in all 50 states and over 40 countries as a nutritional and dietary supplement designed to support overall wellness. ETST's High Grade CBD Rich Hemp Oil is all-natural and derived completely from the federally legal industrial hemp plant. Industrial Hemp (Hemp) is not marijuana and will not get you 'high' and it does not require a medical license of any kind to authorize purchase. It is lab tested multiple times during the manufacturing process, from seed to shelf. This also includes being tested for CBD content, other Cannabinoid content, yeast/mold/fungus, and bacteria like E. coli to ensure safety and top quality. Cannabidiol (CBD) is a naturally occurring constituent of the hemp plant. ETST believes that CBD Rich Hemp Oil awareness today is where Omega 3 and Omega 6 fatty acids were 15 to 20 years ago. ETST goal is to help consumers Worldwide with their overall wellness through advanced formulations with its CBD Rich Hemp Oil and cutting edge nutraceuticals and dietary supplements. CBD Rich Hemp Oil is posed to be the most renowned and effective natural compound and botanical alternative introduced to the nutritional and dietary supplement industry in decades. ETST plans on continuing its research, tests and clinical studies with the University of Central Oklahoma as well as other 3rd party labs in regards to its ETST High Grade CBD Rich Hemp Oil. Consumers worldwide desperately need more effective safe botanical alternatives to help them with their overall health and internal wellness. Modern science has identified over 400 phytonutrients in various parts of the industrial hemp plant. These include hundreds of Terpenoids, Essential Oils and Antioxidants but perhaps the most dynamic are a group of 80 compounds called Cannabinoids that are exclusively found in Hemp and one other place; our bodies. ETST CBD Rich Hemp Oil contains the synergistic Cannabinoids, Terpenoids, Essential Oils and other compounds found in the industrial hemp plant. There are roughly 80 different phyto-cannabinoids, most prominently CBD, CBC, CBG, CBN, and most likely others yet to be effectively identified. In addition to the cannabinoids present in our full spectrum raw industrial hemp oil extracts, there are also many other types of natural molecules and phyto-chemical compounds such as amino acids, sugars, vitamins, fatty acids (including omega 3 & 6), flavanoids, ketones, nitrogenous compounds, alkanes, alcohols, glycosides, pigments, hemp seed oil, water, and terpenes. The most common terpenes in our CBD oils are Beta-caryophyllene, Caryophyllene Oxide, Myrcene, Terpinolene, α Bisabolol, α Pinene, Nerolidol, Ocimene and Phytol. Hemp oil contains more essential fatty acids than any other plant.

Humans are designed with a built-in Endocannabinoid System (ECS). Research shows that many scientists believe cannabinoids work synergistically to support the whole human endo-cannabinoid system (internal and natural human cannabinoid system). It is your body's way of communicating with itself and properly regulating the way every other body system functions from your brain to your toes. The Endocannabinoid System (ECS) has shown to control pain sensation, appetite, temperature regulation, stress reactivity, immune function, and sleep as well as other processes. Even more interesting is that muscle and fat tissue also utilize these receptors to control their processes. Consumers should think of the Endocannabinoid System as one of the body's main control and command centers for tweaking your metabolism's ability to react and adapt to the world around it. Like many other nutrients in our diet, Cannabinoids can become exhausted and in need of steady dietary replenishment. Scientific studies and data show that CBD (Cannabidiol) Rich Hemp Oil as well as all micronutrients (phytonutrients) and phyto-cannabinoids found in the oil work in harmony with the human body's own endocannabinoid system making a positive effect for overall wellness. Hemp oil contains CBD -- a non-psychoactive compound of the plant. There are millions of hemp oil consumers around the world and this number is rapidly rising with an increasing number of reports and studies showing a variety of benefits of hemp oil.

These finding are breakthroughs in this field. With these new studies and test results, ETST has 2 provisional patents and inventions with its CBD Rich Hemp Oil (patent Serial No. 62102538 and patent Serial No. 62061577). Additionally, ETST has a total of ten (10) new claims for its Hemp Oil Enriched with CBD (Cannabidiol) and Hemp Oil Enriched with Proprietary Additives. Partial Abstract of new Patent Serial No. 62102538: A composition having cannabidiol, alone, or as a component of hemp oil, for use in treating or preventing cancer. The composition may include D-limonene, which contributes synergistically to the anticancer efficacy of the composition. On January 26, 2015 ETST announced Positive Test Results of its Product CBD (Cannabidiol) Rich Hemp Oil; In Collaboration with the University of Central Oklahoma, Test Results Demonstrate that CBD Rich Hemp Oil Enhances Immune Function. The results of this preliminary study indicate that with appropriate CBD concentrations, hemp oil can stimulate macrophages to produce TNF α and can also enhance the TNF α production stimulated by LPS. The study illustrated that ETST CBD Rich Hemp was capable of Stimulating and Enhancing Tumor Necrosis Factor alpha (TNFα) Production by Macrophages. Under the sponsorship of Earth Science Tech (ETST), researchers at the University of Central Oklahoma have been investigating the effects of CBD on immune cells with ETST using the ETST CBD Rich Hemp Oil. Led by lead investigator Dr. Wei R. Chen, the team found that ETST hemp oil solution used in appropriate CBD concentrations could stimulate macrophages, an important immune cell, through the production of TNF α. The cytokine TNF α is a key cell signaler in the recruitment of immune cells. Furthermore, they also found that the CBD was capable of enhancing TNF α production by macrophages initiated by other compounds. Dr. Chen's team believes that the effects of hemp oil enriched with CBD on immune cells may be used to improve cancer treatment, particularly in combination with other treatment modalities. In collaboration with Dr. Chen, ETST plans continued studies to determine the effects of hemp oil with CBD on inducing and enhancing anti-tumor immune responses.
