Heal with Us

We offer personalized consultation on a variety of non-psychoactive plant and healing products. 


Our mission is to provide clients the knowledge and natural tools needed to lead a self- directed prevention focused healthy lifestyle: A lifestyle not solely reliant on traditional medicine, but filling in its gaps and empowering clients to complement traditional medicine, striking a balance between traditional and natural health solutions to achieve well being and where possible prevent disease before having to cure it.


– Courses and workshops with experts in plant medicines, nutrition and a broad array of other natural medicine modalities

– A comprehensive array of plant-based medicinals, including full lines of CBD products, essential oils, and a curated selection of medicinal teas and ayurvedic botanicals

– Consultation and growing equipment for the DIY cannabis medicinal grower


The United States has the most technically advanced healthcare in the world. Why has our average life expectancy been declining for 2-3 straight years and why is it lower than citizens of many other developed countries?

Growing evidence points to  an over-reliance on pills (synthetic medicines), processed foods and external environmental factors causing inflammation, stressing our immune systems and compromising our overall health. Fortunately, our bodies have a remarkable capacity to heal themselves with the right natural remedies
