Can CBD help with hay fever?



CBD has well-known anti-inflammatory properties.

While many of us are glad to see the world bloom into springtime, for others it marks the start of the dreaded hay fever season.

While the allergic reaction can occur all year round, late March (when the tree pollen season kicks in) is the most common time, leaving thousands of sufferers with streaming eyes, running noses and itchy skin.

What is hay fever?

The NHS describes hay fever as an allergic reaction to pollen, typically when it comes into contact with your mouth, nose, eyes and throat.

There is no cure or treatment for hay fever, although there are a number of over-the-counter antihistamines that can help alleviate some of the symptoms. Unfortunately, many of these carry side effects – the most common of which is drowsiness – meaning that many people find them difficult to use.

Other remedies include using Vaseline round the nose to ‘trap’ pollen before it enters the airways, wearing sunglasses to protect the eyes and vacuuming regularly to remove pollen from the home.

However, there are some promising studies that cannabidiol could also be used to help hay fever sufferers, with fewer debilitating side effects.

Promising signs

While there have been no human studies so far, a number of animal studies have shown some positive signs. 

In 2013, a study gave a number of guinea pigs an antigen to stimulate a contraction in their throat muscles, which can be a common symptom of hay fever. Researchers found that “cannabidiol reduced … airway obstruction”, adding that CBD “may have beneficial effects in the treatment of obstructive airway disorders”.

Two years later, in 2015, another study looked at the link between the mediation of CB1 receptors and mast cells, which are responsible for releasing the histamines that cause the symptoms of hay fever. Although the results were inconclusive, they suggested that CB1 receptors may mediate the hypersensitivity of the immune system, which in turn could be used to lower histamine levels.

While the specific benefits from CBD for hay fever may need further research, one thing that is for certain is that CBD has well-known anti-inflammatory properties.

These properties can prove invaluable during an allergic reaction, working to reduce any swelling or irritation and limiting further histamine production.

In fact, CBD’s interaction with the human endocannabinoid system has been shown to reduce almost all of the most common side effects that accompany an allergic reaction, such as opening airways to make breathing easier, easing nasal pressure and relieving congestion and mucus.

While more research is needed to find a definitive answer, it appears clear that, even if CBD is not proven to prevent the symptoms of hay fever, at the very least it can ease them.

What’s more, it is a natural alternative to prescription medications, which, in the case of anti-histamines, can bring a number of unpleasant side effects, such as a dry mouth and drowsiness.

With the sniffle season fast approaching, some sufferers may be looking to try a more natural alternative – and CBD could be the perfect solution.  



Combining CBD and CBG for the ultimate entourage effect

How much do you know about the 120 different cannabinoids in the cannabis plant? Browns CBD explains how CBD and CBG combine to offer different benefits



The plant actually produces over 120 cannabinoids with some being equally as impressive for certain issues. Browns CBD explains how CBG and CBD combine for the ultimate entourage effect.

By now you will have surely heard of CBD – the hemp-derived compound that has a plethora of health benefits and is incredibly safe to use.

Another important cannabinoid is CBG (Cannabigerol). This cannabinoid is commonly referred to as the ‘mother of all cannabinoids’ as it is the original molecule that most other cannabinoids are synthesized from.

In simple terms, hemp produces CBGa (the acidic form of CBG) in earlier stages of growth which is then converted within the plant into cannabinoids such as THCa, CBDa & CBCa. This can be seen in the diagram below.

CBG tends to be more expensive than CBD due to the fact that most varieties of hemp yield very low levels of CBG. And crops need to be harvested earlier to obtain significant levels of CBG for extraction. However, new CBG rich varieties of hemp are being developed to achieve greater yields.

CBD and CBG benefits

Studies on the benefits of CBG are fairly limited when compared to those of CBD, but there is some very promising preliminary evidence. Anecdotally, we have found customers to be very impressed with its calming effects on a range of issues.

CBG interacts with the endocannabinoid system differently from CBD. For those of you who don’t know, the endocannabinoid system is a significant bodily system made up of endocannabinoids, cannabinoid receptors and enzymes. This system is involved in the proper maintenance of a wide range of bodily functions.

CBD indirectly interacts with these receptors, whereas CBG directly acts upon them. It is through this differentiation of interaction that we believe CBG can have different effects from CBD. A quick search on Google will highlight what these can be.

Our CBG Hemp Oil is rich in CBG, but also in CBD. It has a 1:1 ratio of CBG to CBD in order to have the most significant impact on the endocannabinoid system. Furthermore, it contains both CBD and CBG in its acidic forms and a wide range of additional cannabinoids and terpenes.

Due to the huge variation of compounds within this product, it tends to have more pronounced effects than standard CBD oils of the same strength. Customers tend to be surprised at just how effective it is with the seemingly low 3 per cent concentration.

We believe this is due to the ‘entourage effect’ which is a phenomenon where compounds interact synergistically which results in stronger effects for the user. This has been demonstrated in several studies.

Study shows legalisation has no adverse effects on neonatal health outcomes

The team of researchers assessed the influence of statewide cannabis liberalisation policies on newborn health



Neonatal: A baby holding a person's finger

A new study on the effects of legalising cannabis for adult or therapeutic use shows no adverse effects on neonatal health outcomes at the population level.

The neonatal study was published in the Journal of Health Economics and shows that legalising cannabis for adult use is not associated with adverse effects on neonatal health outcomes.

The team of researchers from Columbia University, University of North Carolina and Indiana University assessed the influence of statewide cannabis liberalisation policies on newborn health over 12 years starting in 2007.

They discovered that the proportion of maternal hospitalisations from cannabis use disorder increased by 23 percent in the first three years of legalisation with larger percentages in states where commercial sales were allowed. This was accompanied by a decrease of 7 percent in tobacco use disorder hospitalisations.

Legalised cannabis was not associated with any significant changes in newborn health according to the study. Medical cannabis laws had no statistically significant effect on maternal substance use disorder hospitalisations or on newborn health.

Neonatal health

The authors wrote: “There is no statistically significant effect of medical cannabis laws on the proportion of newborn hospitalisations with prenatal exposure to noxious substances, neonatal drug withdrawal syndrome, fetal alcohol syndrome, slow growth, respiratory conditions, feeding problems, congenital abnormalities, low gestational age, low birth weight, or very low birth weight. Likewise, recreational cannabis laws appear to have no effect on these outcomes.”

They concluded, “In absolute numbers, our findings implied modest or no adverse effects of cannabis liberalisation policies on the array of perinatal outcomes considered.” However, they cautioned, “Our null findings do not refute nor support an argument that prenatal exposure to cannabis has negative effects on newborn health outcomes, but rather that state cannabis liberalisation policies are not associated with net changes at the population-level that are statistically detectable or economically meaningful.”

Neonatal studies

Other studies assessing the potential effects of cannabis use during perinatal health are inconsistent. Some studies link cannabis use to lower birth weights but failed to adjust methods to account for contributing factors such as tobacco smoking.

A study conducted during the pandemic revealed that cannabis use among pregnant women has increased during lockdown.

Researchers from Kaiser Permanente analysed figures of pregnant women consuming cannabis in Northern California during the pandemic to the numbers from the previous year.

The study involved analysing urine toxicology tests of more than 95,000 women having their first prenatal visit in Northern California Kaiser Permanente. They collected the tests between January 2019 and December 2020 before comparing them to tests from 15 months prior to the start of the pandemic. The results showed a 25 percent increase in the rate of cannabis consumption. Prior to the pandemic, the rates of pregnant women using cannabis were at 6.75 percent. This rose to 8.14 percent during the lockdown.

Clint Eastwood wins $6m in damages from CBD company in lawsuit

The actor’s image was used to promote a CBD company that he had no affiliation or promotional ties with.



Clint Eastwood: A row of glass bottles with yellow CBD oil them

Clint Eastwood is just one of many celebrities who have had their images used to promote CBD companies in recent years despite not having an affiliation with the brand.

The actor Clint Eastwood was awarded $6.1 million on Friday in a lawsuit against a Lithuanian CBD company that was accused of using his image and likeness to endorse their products. Eastwood filed two lawsuits against three CBD manufacturers and marketers last year after they claimed he endorsed CBD products in an online article. He also filed against 10 online retailers who were accused of manipulating search results through their meta tags.

Clint Eastwood lawsuit

Eastwood’s lawyers filed an amended complaint in February 2021 against Mediatonas UAB, the company that owns the website where the stories appear. While the court was in agreement that he and Garrapata, the company that owns his image, were entitled to damages, they did not allow for defamation claims noting that the language used was not libellous. The company failed to respond to the summons issued last March.

Eastwood has no connection of any kind whatsoever to any CBD products, the plaintiffs said in court.

The original complaint, filed in July 2020, named as defendants the companies whose products were being advertised in the article. In February, Eastwood’s lawyers filed an amended complaint against Mediatonas UAB, the company that owns the websites where the false stories appear. They will also have to pick up the costs for Eastwood’s legal team.

The original story shared a false online interview that featured the actor claiming he had left filming to start a CBD line.

Clint Eastwood is not the only celebrity to have their image used to promote CBD brands they are not affiliated with. Tom Hanks, Russell Brand and Mary Berry have all found themselves advertising products online.

Celebrity endorsements

Celebrity endorsements can be used to make customers feel more confident about buying a product or a particular brand. Some celebrities do actually endorse CBD products such as Claudia Winkleman for Cannaray. She signed a deal with the company after revealing that she used CBD to combat stress during lock down.
