Frequently Asked Questions

What is hemp?

Hemp, which is often referred to as industrial hemp, is a variety of the Cannabis sativa L. plant. Many people get hemp and marijuana confused for each other since they come from the same species of plant, but one of the main distinguishers is hemp’s non-psychoactive and non-intoxicating properties. On the other hand, marijuana is psychoactive due to greater amounts of tetrahydrocannabinol (THC). Hemp can be grown and used for many different types of products, ranging from fabrics to CBD oil, for example. 

What is a hemp flower?

Hemp flowers are the buds found on female hemp plants upon reaching full bloom. Many people consume CBD-rich hemp flower buds through vaping or smoking the dried flowers.

What are cannabinoids?

The Cannabis sativa plant has many cannabinoids that are naturally-occurring compounds of various classes. There are many substances found in the Cannabis plant--THC and cannabidiol (CBD) being the more well-known classes of cannabinoids. 

What is CBD? 

CBD stands for cannabidiol. This is a naturally-occurring, non-psychoactive compound found in the hemp or Cannabis plant. There are many ways to consume CBD including edible gummies; capsules; hemp oil; salves and topicals; and smoking hemp flower buds. 

How is CBD grown and prepared?

You start with growing CBD-rich hemp plants and then collect the matured hemp flower bud in the harvest season. At Kingdom Harvest we use only the flower, or bud. Our hemp is non-GMO and free of herbicides and pesticides. After harvesting, we prepare the hemp plant in a climate-controlled environment to dry the leaves and flowers.

CBD oil extracted from marijuana, Cannabis that has a high amount of THC, is only legal in the Medical Cannabis States. Learn more about CBD legality by state. 

What does CBD do?

Our bodies have an endocannabinoid system that can resemble the chemical structure of CBD. CBD influences the endocannabinoid receptors, in this case CB1 and CB2. Once these receptors are activated, people may start to see the many health benefits associated with CBD. CBD may also impact non-cannabinoid receptors. More research needs to be done to explore the scientific relationship between the endocannabinoid system and CBD. 

What are the benefits of CBD?

How do I use CBD oil?

Consuming Kingdom Harvest’s CBD sublingual oils are very easy. The bottle comes with a  graduated dropper so you can accurately measure your serving. You take the dropper and administer the oil under your tongue and hold it there for 30 to 60 seconds before swallowing. The dosage and frequency you take depends on your needs, weight and physiology overall. We advise all of our customers to “Start low and go SLO” with our sublingual oil (SLO). 

Our CBD oils come in various strengths and flavors to select from and we offer recommended dosage instructions for each. Let’s take a look at our popular Whole-Spectrum Hemp Extract; each 30 mL bottle contains 300mg of CBD. In this case, we recommend a serving of 0.25 ml, twice daily.

While CBD my help you feel relaxed, it does not make you feel “high” because CBD is not psychoactive. THC is the psychoactive compound found in the cannabis plant and all Kingdom Harvest products contain less than 0.3% tetrahydrocannabinol (THC), as required by the 2018 Federal Farm Bill.



How does CBD make you feel?

The effect and sensation of CBD varies by the potency, product and purpose in addressing each ailment. Many people report feeling calm and restoring a balance to optimize their daily health when taking CBD. If, for example, you are experiencing pain, our CBD pain salve can aid in making you feel relief. If you are having trouble falling asleep and staying asleep, our Sleep Support Pills can provide the relaxation you need at bedtime.*

How long does CBD stay in your system?

Generally speaking, CBD can stay in your system for a few hours. There are several factors that affect how long CBD lasts:

  • Your dosage amount 
    • How often you take CBD
    • The form of CBD
    • The method used to consume
    • Your body weight and body
    • The amount of food you’ve eaten

    If you digest hemp gummies for example, that will take a different amount of time to start feeling the effects versus taking the pure oil that’s absorbed under the tongue. 

    Does CBD have any side effects?

    A 2017 survey on the side effects stated that “the favorable safety profile of CBD in humans was confirmed” when examining clinical data. The World Health Organization (WHO) has stated that CBD exhibits no effects indicative of any abuse or dependence potential in humans. In circumstances like this, side effects could be changes in appetite, weight loss and fatigue. 

    Can I consume CBD if I take other medications?

    If you have concerns with taking CBD while using other drugs, it’s recommended you consult with your doctor or healthcare professional. Research from WHO suggests that some of the adverse effects of CBD observed in the clinical studies may relate to drug interactions, when it came to epilepsy treatment, but more research is needed.
