How CBD Helps With Endometriosis Pain

Endometriosis is an often painful ailment where the tissue that usually lines the insides of your uterus grows outside(1).   

The pain is sometimes difficult to alleviate without surgery, which often produces intolerable side effects(2).   

Based on a study from the Journal of Pain, the endocannabinoid system (ECS) may affect uterine function and dysfunction. Thus, the researchers hypothesized that the ECS may be involved in endometriosis and associated pain(3)

The endocannabinoid system is present in almost all parts of the body and functions by maintaining homeostasis(4)

Homeostasis is the process where living things maintain stability(5)

Cannabidiol (CBD), which is an active element of cannabis(6), works by interacting with the ECS(7)

The ECS is composed of cannabinoid receptors, namely, CB1 and CB2 receptors found on cells throughout your body(8)

CB1 receptors play a significant role in pain sensation(9). They may be expressed on both the somata (body of an organism) and fibers of the sensory and sympathetic neurons that innervate ectopic growths(10).    

The findings suggested that the endocannabinoid system may contribute to mechanisms underlying the pain associated with endometriosis. The ECS may also affect the peripheral innervation of the abnormal growths(11)

Note that the human body naturally produces endocannabinoids that interact with the cannabinoid receptors(12)

However, if there is a shortage of endocannabinoids, plant-based cannabinoids like CBD and tetrahydrocannabinol (THC) may mimic their actions(13)

 THC is the primary psychotropic congener in the cannabis plant that produces a euphoric high. CBD, on the other hand, is non-psychoactive(14)

When there is an endocannabinoid deficiency, administering CBD and THC may help the endocannabinoid system maintain its proper function(15)

However, measuring the number of CB receptors stimulated and how each phytocannabinoid enters the bloodstream is complex(16)

A national online survey conducted in 2019 focused on self-management strategies of Australian women with endometriosis(17)

Among the many self-management strategies Australian women used to alleviate their symptoms, hemp or CBD oil displayed one of the highest pain relief scores(18)

This result may be promising. Still, significant research must be done to understand the impact of the interaction between CB receptors and cannabinoids like CBD.

More studies are necessary to determine CBD’s therapeutic effects and its ability to alleviate endometriosis pain

Benefits of Using CBD for Endometriosis Pain

Endometriosis may cause pain and discomfort due to the abnormal growth of the endometrial tissue(19)

CBD may help with inflammation and pain(20). Thus, CBD’s anti-inflammatory and pain-relieving properties may be promising for endometriosis

A cross-sectional online survey from the BMC Complementary Medicine and Therapies reported that CBD oil was one of the most highly rated self-management strategies based on the female participants’ personal experience(21).  

Numerous clinical trials involving cannabidiol’s purported benefits on chronic pain have been conducted since the early 2000s(22)

A study published in the journal Antioxidant reviewed the main biological effects of cannabidiol and its synthetic derivatives, focusing on CBD’s antioxidative and anti-inflammatory properties(23).

The researchers hypothesized that CBD may help with diseases associated with oxidative stress(24).

For this reason, cannabidiol’s antioxidative and anti-inflammatory properties may help women with endometriosis

Note that endometriosis not only causes pain. The condition may also lead to infertility(25)

Research from Oxidative Medicine and Cellular Longevity noted the role of oxidative stress, defined as a disproportion between antioxidants and reactive oxygen species (ROS), on endometriosis(26)

ROS plays a significant role in the modulation of cell survival and inflammation-related factors(27)

Oxidative stress plays a pivotal role in infertility due to the decreased level of antioxidant mechanisms. Meanwhile, excessive ROS may reduce the likelihood of fertilization in IVF or in vitro fertilization because it causes an environment unsuitable for normal female physiological reactions(28).

IVF is an assisted reproduction procedure where a woman’s egg and a man’s sperm are combined in a laboratory dish(29)

Aside from CBD’s anti-inflammatory properties, this non-euphoriant compound also contains analgesics with a CB1 receptor antagonist and endocannabinoid modulating effect(30)

Thus, CBD’s analgesic properties may help women with endometriosis in terms of pain management

These studies are still inconclusive. Therefore, more research is needed to verify the efficacy of CBD on endometriosis

How Long Does CBD Take to Help With Endometriosis Pain

Inhaling CBD using vape pens is the quickest way to benefit from the effects of cannabidiol(31)

However, vaping should be done with caution as this ingestion method may damage your lungs(32)

Meanwhile, taking substances under the tongue also ensures prompt delivery of CBD into your system(33)

Most CBD tinctures or CBD oil products may include a calibrated dropper which you can use to dispense the content straight into your mouth. Usually, cannabidiol’s onset is around 15 to 30 minutes via this method(34)

For CBD topicals, the onset is also relatively quick (10 to 15 minutes), and the effects usually last from two to four hours(35)

How Long Will CBD Help With Endometriosis Pain

Bioavailability is when a substance becomes entirely available to its intended biological destinations(36)

A systematic review published in Frontiers Pharmacology determined that cannabidiol’s bioavailability after smoking is 31%(37)

 The bioavailability is zero for the topical application since it does not allow the compound to enter the bloodstream(38).   

Meanwhile, CBD’s half-life is between 1.4 and 10.9 hours after an oromucosal spray, two to five days after chronic oral administration, and 24 hours after intravenous medications (administered through the veins)(39)

A half-life means the estimated time it takes for a drug in your system to be reduced by 50%(40).

Risk and Side Effects of Using CBD for Endometriosis Pain 

Cannabidiol is relatively safe for use(41). However, it may also have some side effects such as:

  • Dry mouth
  • Diarrhea
  • Reduced appetite
  • Drowsiness
  • Fatigue 

CBD Dosage

Most CBD brands may provide a recommended dosage for every CBD product they have.

Research from Current Drug Safety stated that humans may tolerate chronic use and high doses of CBD up to 1,500mg per day(42)

Still, it is recommended that you speak with a physician before administering any CBD product to manage endometriosis pain

Taking CBD Oil for Endometriosis Pain 

CBD products are available in tinctures, vapes, edibles, and topicals, like balms and creams. 

When choosing the best CBD oil for endometriosis pain, below are a few things you need to consider:

  1. Make sure to go for high-quality CBD products if you want to maximize the benefits of CBD. Always check the ingredients list and choose either full-spectrum CBD oil or CBD isolates. Remember that for a CBD product to be considered full-spectrum, its THC level must be less than 0.3%. Moreover, it must have all the extracts of cannabis plants. Meanwhile, CBD isolates are a pure form of cannabidiol(43).
  2. Look for any disclaimers, certificates of analysis (CoAs), and lab test results.  

Legality of CBD 

The 2018 Farm Bill legalized the commercial use of industrial hemp on a federal level in the U.S(44).

The bill noted that Cannabis sativa plants with not more than 0.3% THC are considered industrial hemp(45).

Product Frequently
Asked Questions

  • How can CBD help with endometriosis pain?

    When a woman has endometriosis, the normal tissue around the endometriosis implants becomes scarred and inflamed(46)

    CBD has anti-inflammatory properties and also contains analgesics(47). Thus, CBD may help with endometriosis pain.

  • What evidence or research exists to say that CBD helps with endometriosis pain?

    Research from the Antioxidant journal examined cannabidiol’s antioxidative and anti-inflammatory properties(48)

    The researchers hypothesized that CBD may help with diseases associated with oxidative stress(49)

    Oxidative stress is associated with endometriosis(50). Thus, CBD may be promising in the management of endometriosis pain.

  • Are there any pieces of evidence that CBD can make endometriosis pain worse?

    There is no direct evidence linking CBD’s effect on making endometriosis pain worse.

  • Will CBD interact with any medications I may be taking for endometriosis pain?

    Yes. There is a probability that CBD may interact with any medication you are taking for endometriosis. Remember that although CBD is often well tolerated, it may also carry some risks. You may experience diarrhea and dry mouth(51).

    Thus, seeking medical advice is necessary, especially if you are considering CBD or medical marijuana for optimal wellness. 

    A physician may advise you regarding possible drug-to-drug interaction.

  • Are there other treatments I should consider alongside CBD to help with endometriosis pain?

    If you have endometriosis, several treatment options are available for pain relief.  

    You may take nonsteroidal anti-inflammatory drugs (NSAIDs) or ibuprofen to calm endometriosis and help alleviate painful menstrual cramps(52)

    However, CBD may interact with these painkillers. Thus, you must talk with a physician before using CBD with other endometriosis treatments or supplements for self-care.

  • Can I fail a drug test if I use CBD for endometriosis pain?

    No. Based on clinical trials, the oral administration of cannabidiol does not result in detectable THC blood concentrations(53)

    Therefore, the oral administration of CBD alone should not result in a positive drug test.

  • What is the dosage for endometriosis pain?

    CBD as medication has not been approved by the U.S. Food and Drug Administration (FDA). Thus, there is no official dosage guideline for CBD.

    However, the general rule is to start low and go slow and then adjust the dosage accordingly until you achieve the desired effects.

  • What are the symptoms of endometriosis?

    Endometriosis is caused by the growth of the endometrium outside your uterus (womb). This condition commonly involves your fallopian tubes and ovaries

    Common signs include(54):

    • Pain with bowel movement 
    • Infertility 
    • Lower back pain 
    • Pelvic pain 

    Risk factors include heavy periods and short menstrual cycles, which may be regulated by apoptosis (eliminating unwanted cells)(55)

    Aside from pain medication, your physician may also advise hormone therapy(56). Furthermore, they may recommend a laparoscopy to detect any lesions(57)

    Endometriosis may sometimes be confused with ovarian cysts or any condition that can cause pelvic pain(58)

    However, defects in the immune system and genetics may play a vital role in determining whether a woman will develop this condition(59)

    If endometriosis invades organs near the uterus, it is called deep-infiltrating endometriosis(60).

  • What is the entourage effect?

    It is the positive effect that comes from terpenes and all of the cannabis plant components(61). This phenomenon enhances cannabis’ purported benefits.
