Colds are rampant right now, and everyone is trying to stay healthy using tried and tested home remedies and avoid strong medications and antibiotics.

As mentioned in the previous blog post, our own behavior (e.g., maintaining distance, washing hands, dressing warmly, etc.) is also a factor in staying healthy during this cold and wet time of year. However, viruses and bacteria are easily spread through droplet infection in crowded spaces, on trams, or airplanes, posing a risk to us. I can't always avoid this attack by microorganisms. But I can ensure that my immune system is as strong as possible right now. Because illness only develops when the balance between the attackers (microorganisms) and the defense (immune system) is disrupted.

In addition to a number of secondary plant compounds, ginger is particularly suitable for supporting the immune system due to its anti-inflammatory and antibacterial properties and can help with colds.

Ginger is rich in essential oils (over 150 components) as well as pungent compounds such as gingerols , which are partly responsible for its distinctive fruity-spicy flavor. It has not only been used for centuries in alternative Traditional Chinese Medicine (TCM) and Ayurveda, but is now also the subject of intensive research at the Chair of Naturopathic Medicine at the University of Freiburg.

The effects of the antioxidant and anti-inflammatory substances gingerol, shogaols, paradol, and zingerone have now been scientifically elucidated and involve specific signaling pathways within the cell and the reduction of pro-inflammatory messenger substances (cytokines) (Frontiers Nutrition 2024). Further studies have demonstrated a 30% increase in the activation of white blood cells (immune cells) (Anderson, Mol Nutr Food Res, 2022). The increased blood flow in the mucous membranes supports the body's defense mechanisms, particularly in the throat, nose, and neck area. It is especially effective during the cold phase of flu-like infections or when we are feeling cold or have a chill.

Ginger can be consumed in various ways. Traditionally, ginger tea is enjoyed, as current studies indicate it has the highest medicinal effect. The hot water releases many of the pungent compounds from the ginger, allowing the root to release its full potency. According to a study by the Leibniz Institute at the Technical University of Munich, maximum bioavailability is reached just 30-60 minutes after consumption, as significant amounts of the pungent compounds can then be detected in the blood (Anderson, Mol Nutr Food Res, 2022). To prepare ginger tea, simply boil thin slices of fresh ginger root in hot water. The longer the tea steeps, the spicier it becomes. Since many important beneficial compounds are found primarily under the peel, ginger should not be peeled and is therefore best consumed organically.

Homemade ginger shots typically contain lemon, honey, and cinnamon or turmeric and pepper, in addition to ginger. When buying ginger shots, it's essential to check the sugar content and any other preservatives, as these are often very sweet and contain added fruit juices and sugar.

Ginger not only helps with colds, but also activates intestinal activity, improves many forms of nausea, helps with bloating and flatulence, and can even lower cholesterol levels.

Gingerols are similar to acetylsalicylic acid and can therefore also help relieve pain. When applied externally, the essential oils and pungent compounds can have a warming, antispasmodic effect.

There are only a few things to keep in mind when consuming ginger. People with sensitive stomachs should be careful. Drinking liters of ginger tea on an empty stomach can be too irritating. In this case, it should only be consumed in moderation or, ideally, with or directly after a meal.

Ginger can cause irritation in sensitive skin. Therefore, direct skin contact should be avoided if you have skin problems or open wounds.

However, ginger is definitely a small miracle weapon for strengthening the immune system.

But there are, of course, a number of other secondary plant compounds that we at PDB use with great success in our formulations, such as our immune supplement. And when it comes to the immune system, the gut should by no means be forgotten and ideally strengthened with our Core Balance . Especially in winter, it's important to consider vitamin D levels, and here you can specifically support them with our balanced vitamin D3/K2 combination.
