What Most Doctors Won’t Tell You About Colds and CBD

Editorial Team

Very few people make it through the winter without an annoying cold or a runny nose. Some of us will also catch the flu.

With winter approaching, it’s important to know how you can protect and boost your immune system.

Sure, you can go down the standard route, get a flu vaccine, that is laden with toxic chemicals, or you can shove conventional medicine down your throat once you’re sick. Another option is to let it run its course and protect your system using CBD.

What most doctors won’t tell you is that in most cases it’s best to let colds and cases of flu run their course while using natural medication to help ease many symptoms. In most cases, these natural remedies, such as CBD, could even help boost your immune system, preventing your body from catching these viruses.

How Do We Get Colds and Flus?

That is an extremely complicated question to answer, but in most cases, it comes down to the following reasons:

  1. We are constantly in confined areas with other people who spread germs. Viruses such as influenza become airborne when someone coughs, and it only takes a few breaths to become sick.
  2. Viruses causing most respiratory infections are constantly mutating, and unfortunately, our immune systems have trouble dealing with these ever-changing germs.
  3. Viruses can live on non-porous surfaces for hours on end. If you touch a table or pen, recently touched by a sneezing person, you’re likely to get sick.

How Do These Viruses Affect Our Body?

To understand how a cold affects our body, it’s important to understand that colds and flus are the outcomes of viruses in our body. These viruses are microscopic particles of genetic material, each coated with a thin layer of protein. Unlike the natural cells in your body, these viruses are not able to reproduce on their own, but instead, use the machinery and metabolism of your cells to produce multiple copies of themselves.

Once the virus enters a cell, it will either use that cell’s resources to replicate itself, eventually breaking the cell in search of a new cell, or, incorporating itself into the DNA of your cell. This allows the virus to be passed down through natural genetic duplication (mitosis) and cellular division (cytokinesis).

Why Let a Flu or Cold Run Its Course?

In most cases, the viruses that cause colds and cases of the flu will affect weak cells, ones that are already burdened and contain excessive toxins. These are cells that your body would anyway prefer to get rid of – and it’s natures way of helping. Most doctors would argue and prefer to prescribe some form of medication that they are affiliated with, but a cold or flu is actually a natural event that helps your body to identify damage cells, destroy and eliminate them. This means that the best remedy is to let it run its course.

So Why Protect Your Body Using Cannabis?

With that said, it doesn’t mean that you have to catch a cold or flu intentionally. If you look after your body, by living a healthy lifestyle and resting well, your cells will be strong enough to avoid infection. You simply won’t have weak cells that need to be flushed out of your system. And for that, we sometimes need a natural helping hand. Remember, most people do not die from viruses, but bad colds and the flu certainly do cause a lot of pain and discomfort.

Cannabis and especially its two major compounds, CBD and THC, have been known to ease many symptoms of the common cold. CBD is a potential anti-inflammatory which can fight pain, such as sinus pressure, while THC can reduce common pains associated with these viruses which allow the body to rest and self-heal. While smoking marijuana isn’t recommended when sick as it can cause respiratory irritation, other forms of the plant can be used such as CBD oil . Furthermore, CBD has become a favorite item in recent years for its immune strengthening properties.

According to Dr. Robert J. Melamede, Chairman of the Biology Department of the University of Colorado,

“Contemporary antiviral medical technology is currently not able to meet the world’s immediate challenges,” said Melamede. “We believe that cannabis extract-based medicines can help to reduce influenza deaths.”

Dr. David Allen thinks that,

“Cannabidiol (CBD), may offer control of the immune system and in turn, protect from viral infections. Cannabis has already been seen to inhibit fungus and bacteria and can be considered a new class of antimicrobial because of the different mechanism of action from other antimicrobials.”

When the immune system launches an attack on a virus, it causes an inflammatory response that produces flu or cold-like symptoms. While the body uses its own endocannabinoids to moderate the immune response, it’s not always capable of controlling the inflammatory process. Cannabinoids in cannabis help in this aspect by giving the natural endocannabinoid mechanism a boost. Also, constant use of extracts may help to keep your body intact helping to prevent a future attack.

Final Thoughts About CBD and Colds

As colds and the flu are both caused by viruses, antibiotics are, in most cases, not required. They may make you feel better because they have a mild anti-inflammatory effect, but this is far outweighed by the negative impact that they have on the friendly bacteria throughout your digestive tract. If you really require help with pain management during a cold or flu, CBD oil could work as an effective treatment.

If you are new to cannabis and looking for a few trusted CBD brands, the following few might be a good place to start.

Can you use CBD to treat the common cold or flu? Here are a few interesting tidbits of information that your doctor may not be telling you.

Common Cold Got You Down? Consider Cannabis as a Remedy

“The study, titled “Cannabinoids and Viral Infections,” concluded that cannabinoids such as CBD, which can be derived from marijuana or hemp plants, may be helpful in dealing with persistent viral infections”

The next time you find yourself suffering with a common cold, you might consider reaching for a product like CBD to help with symptoms such as headaches, congestion and lack of sleep. Some patients also find CBD products beneficial for treating the aches and pains associated with the flu.

CBD As Anti-Inflammatory

There is no cure for the common cold, so the best you can hope for is to treat the symptoms and get plenty of rest while you wait for the virus to pass and take precautions so your cold doesn’t develop into something worse. The non-psychoactive cannabinoid that is legal in all 50 states, CBD has anti-inflammatory properties that may help with respiratory congestion and other symptoms, including pain. CBD is generally well-tolerated and very low in toxicity. CBD can also interact with other medications such as blood thinners, so consult your doctor if that might be an issue.

Scientific evidence is mixed

Scientific evidence is limited on the impact of CBD on viral infections such as a cold, and one study published by the National Institutes of Health came up with a decidedly mixed conclusion, as outcomes varied depending on the virus involved. The study, titled “Cannabinoids and Viral Infections,” concluded that cannabinoids such as CBD, which can be derived from marijuana or hemp plants, may be helpful in dealing with persistent viral infections. But in rare cases, cannabinoids were suspecting of compromising or limiting the body’s natural immune response.

The study summarized research done on a wide variety of viruses, including serious diseases. If you suspect you have something more than a common cold, you should always seek medical attention.

A wide variety of products to choose from

CBD is available in a wide variety of delivery mechanisms, including pill form, edibles, oils, and topical creams that can be applied for any aches and pains. You can even find CBD bath salts or bath bombs, so you can take a relaxing and therapeutic steam bath while ingesting a dose of CBD. Another idea is to try one of the CBD teas now on the market, or perhaps add some CBD honey to your existing tea.

Look For CBD Only Products

The federal government generally turns a blind eye to CBD sales, but the industry is young and lightly regulated, so you may need to experiment to find products that are consistent and effective for you. One issue is that it’s hard to know whether the product you buy has the amount of CBD promised on the label. A University of Pennsylvania study analyzed 84 products from 31 different companies and found nearly half had more CBD than indicated, while 26 percent had less CBD than indicated. Some CBD products may contain significant amounts of THC that can cause intoxicating effects, although reputable producers should say so on the label.

Common-sense guidelines

While CBD might be good for colds, THC can suppress the immune system, so you should probably avoid it until you feel better. And it’s pretty much common sense that you don’t want to be smoking while you are sick with a cold – your respiratory system is already compromised by your illness, and you certainly don’t want to spread the sickness by passing a joint or a vape pen.

A cold can make you feel miserable, but the symptoms generally pass in a week or two. Take care of yourself, get plenty of rest, and try a few supplements along with the chicken soup to see if there’s something that makes you feel better.
