CBD, short for cannabidiol, is a naturally occurring compound found in the cannabis plant and widely studied for its potential wellness applications. Unlike THC, CBD does not produce intoxication. Instead, researchers are studying how CBD interacts with the body’s endocannabinoid system (ECS), a biological network that helps regulate processes such as sleep, mood, inflammation, and immune response.1
Interest in CBD has grown significantly over the past decade among consumers, wellness practitioners, and researchers. Today it is commonly found in wellness clinics, pharmacies, and health-focused retail environments, alongside a growing body of scientific research.
For many people asking “what is CBD?”, the answer begins with understanding how cannabinoids interact with the body’s endocannabinoid system. This guide explains what CBD is, how it works in the body, and what current research suggests about its potential role in wellness.

Scientific Review Note
This article is based on publicly available scientific research related to cannabinoids and the endocannabinoid system. Sources include peer-reviewed journals, academic publications, and regulatory references listed in the bibliography at the end of this article.
The content is intended for educational purposes and reflects current research as of the most recent update.
CBD and the Cannabis Plant
CBD is a phytocannabinoid, meaning it is a cannabinoid produced by a plant.
It occurs naturally in both hemp and marijuana varieties of the Cannabis sativa plant. Most commercial CBD products are derived from hemp, which contains very low levels of THC, regulated at less than .3% in the United States.
The cannabis plant produces more than 100 known cannabinoids, including:
- THC (tetrahydrocannabinol) — responsible for marijuana’s psychoactive effects
- CBD (cannabidiol) — non-intoxicating and widely studied
- CBG (cannabigerol) — sometimes called the “mother cannabinoid”
- CBN (cannabinol) — a cannabinoid currently being studied for calming properties
Scientific interest in cannabinoids expanded significantly after researchers discovered the endocannabinoid system in the early 1990s.2

CBD vs THC: Key Differences
While CBD and THC are both cannabinoids derived from the cannabis plant, they interact with the body’s endocannabinoid system in different ways.
THC
• binds strongly to CB1 receptors in the brain
• produces the psychoactive “high” associated with marijuana
CBD
• does not produce intoxication
• interacts more indirectly with the endocannabinoid system and has greater activity around CB2 receptors, which are found more in the body and immune system
This difference is important for many wellness consumers who want the potential benefits of cannabinoids without the intoxicating effects of THC.
Is CBD the Same as Hemp Oil?
CBD and hemp oil are often confused but are not the same thing.
CBD refers specifically to the compound cannabidiol, which is extracted from the plant, whereas hemp oil, sometimes called hemp seed oil, is pressed from the seeds and naturally contains little to no CBD.
While both come from the same plant family, they have different compositions and uses. Hemp seed oil is typically used in nutrition and skincare products, while CBD products are formulated to deliver cannabinoids that interact with the body, via numerous delivery methods such as tinctures, topicals, or edibles.
How CBD Works in the Body
To understand why CBD has attracted so much scientific interest, it helps to first understand the system it interacts with inside the body.
The Endocannabinoid System (ECS)
The ECS is a biological signaling network found throughout the human body, as well as many other animals. It helps regulate a wide range of physiological processes, including:
- Sleep
- Mood
- Appetite
- Inflammation
- Immune response
- Pain perception
The ECS consists of three primary components:
Endocannabinoids
Naturally produced molecules in the body, including anandamide and 2-AG.
Receptors
The most well-known receptors include:
- CB1 receptors —primarily located in the brain and central nervous system
- CB2 receptors — primarily found in immune cells and peripheral tissues
Enzymes
Enzymes break down endocannabinoids once their signaling role is complete.
Together these components help the body maintain homeostasis, or internal balance.3,4 Researchers believe the ECS also plays a role in helping the body adapt to internal and external stressors.
CBD appears to interact with the ECS indirectly. Rather than binding strongly to CB1 or CB2 receptors like THC, CBD may influence receptor signaling and interact with other pathways including serotonin and TRPV1 receptors.2,5,6

The endocannabinoid system (ECS) includes signaling molecules, CB1 and CB2 receptors, and regulatory processes that help the body maintain internal balance.
Potential Wellness Applications of CBD
Research into CBD is ongoing, and scientists continue studying how cannabinoids interact with biological signaling pathways throughout the body.
CBD products are not intended to diagnose, treat, cure, or prevent any disease, but several areas have attracted significant research attention.
Inflammation Response
Researchers are exploring how cannabinoids interact with inflammatory pathways and immune signaling.2,7
Sleep and Relaxation
Sleep quality is one of the most common reasons people explore CBD. Early research suggests CBD may support relaxation and sleep regulation.8,9
Mood and Stress Response
Researchers are also studying how CBD may influence emotional balance and the body’s response to stress through serotonin-related pathways.1,10
Localized Comfort
CBD topical products such as oils and balms are often used for localized application to muscles and joints and are of interest to wellness practitioners including chiropractors and massage therapists.5,11

Common Ways People Use CBD
CBD products are available in several formats.
Tinctures
Liquid extracts placed under the tongue for relatively fast absorption.
Capsules
Pre-measured servings similar to traditional supplements.
Topicals
Creams, balms, oils, lotions or salves applied directly to the skin.
Edibles
Products such as gummies or infused beverages.
Pet Products
Specially formulated CBD products designed for animals.
The best format depends on personal preferences, wellness goals, and guidance from a qualified professional.

Is CBD Legal?
In the United States, the 2018 Farm Bill federally legalized hemp-derived CBD products containing 0.3% THC or less, significantly expanding access to hemp-derived cannabinoids.
While this legislation significantly expanded the CBD market, state regulations may still vary. International CBD laws also differ by country.12,13,14
Safety and Considerations
CBD is generally considered well tolerated, though responses may vary.
Some individuals report mild side effects such as:
- Fatigue
- Appetite changes
- Digestive discomfort
If you are exploring CBD, consider the following:
Consult a healthcare professional
CBD may interact with certain medications. Individuals who are pregnant, nursing, or taking prescription medications should consult a healthcare professional before using cannabinoid products.
Look for third-party lab testing
Certificates of Analysis (COAs) help verify cannabinoid content, purity, and product safety. Third-party lab testing acts as the “receipt” that validates the ingredients and quality of CBD products. My X Wellness provides these reports for every batch.
Start low and go slow
Start with 10–50 mg of CBD per day for 1–2 weeks, then double the dose for another 1–2 weeks. Continue increasing gradually in this way until the desired effects are achieved.

How Long Does CBD Take to Work?
The time it takes for CBD to produce noticeable effects can vary depending on several factors, including the product type, serving size, individual body chemistry, and condition being treated.
Different delivery methods influence how quickly CBD starts to work:
Tinctures (sublingual)
Often effects can be felt within 15–45 minutes when placed under the tongue and swallowed. The longer it is held in your mouth the faster it will start to work and more CBD will be absorbed.
Capsules and edibles
Typically take 30–90 minutes, as they must pass through the digestive system.
Topicals
Applied directly to the skin and generally used for localized application rather than whole-body effects. Relief can sometimes be felt immediately.
For all delivery methods individual responses can vary, and many people experiment with different products and serving sizes to determine what works best for their needs.
