We explored whether elderberry could help reduce the duration and severity of colds for economy class passengers traveling internationally. In a well-structured randomized, double-blind, placebo-controlled clinical trial involving 312 participants, we looked at how a standardized elderberry extract affected respiratory health during air travel.
Participants tracked their cold episodes, duration, and symptoms in daily diaries, using a scoring method to quantify their experiences. They also completed surveys about their upper respiratory symptoms and quality of life at different points: before traveling and four days post-travel.
While we noted that the group taking the placebo experienced more cold episodes, the difference wasn't statistically significant. However, those taking elderberry had a significantly shorter duration of cold days and a lower average symptom score overall, suggesting that elderberry may significantly lessen the impact of colds during air travel.
Further research is essential to validate our findings and to better understand the broader health benefits of elderberry, both physical and mental.

We explored the effects of ascorbic acid, commonly known as vitamin C, on cold tolerance in tomato seedlings. In our study, we discovered that applying vitamin C significantly boosts the seedlings' ability to handle cold stress.
By enhancing the antioxidant defense system, vitamin C treatment increased the enzyme activity in the seedlings' leaves. Additionally, it raised levels of important compounds such as proline, sugar, and abscisic acid, all of which play crucial roles in plant stress responses.
Our observations showed that vitamin C also protects the photosynthesis system of tomato seedlings. This implies that it helps maintain chlorophyll function, which is critical for the plant's overall health, especially under cold conditions.
Moreover, we found that vitamin C treatments led to increased expression of genes linked to antioxidant enzymes and cold response mechanisms. Overall, our findings suggest that exogenous vitamin C is a beneficial approach to improve cold tolerance in tomatoes and may provide helpful insights for farmers looking to cultivate hardier varieties during colder months.

Zinc enhances rice cold resistance
Effects of different cold-resistant agents and application methods on yield and cold-resistance of machine-transplanted early rice.
We explored the impact of zinc-amino acids chelate on cold stress resistance in machine-transplanted early rice. Our investigation included other cold-resistant agents like uniconazole and abscisic acid, but we found zinc to be particularly effective. When applied during the regreening stage, zinc notably enhanced rice growth by promoting tillering and increasing the leaf area, which led to better yields.
We noted that zinc-amino acids chelate improved antioxidant enzyme activities, which are crucial for helping rice withstand cold temperatures. The yield of rice treated with zinc was approximately 9.22% higher than with uniconazole and 7.14% higher than with abscisic acid.
Additionally, we observed that using 750 g/ha of zinc-amino acids chelate during the transplanting and regreening stages yielded the best results. The timing of the application played a critical role, as spraying during these specific phases maximized both yield and cold resistance.
Overall, zinc treatments stand out as a promising option for improving cold stress resilience in early rice, making it a key consideration for farmers dealing with cold climate conditions.

Cuts the length of cold and upper respiratory congestion within 3 days. It significantly shortens the duration of the cold and upper respiratory infection.
Cold is a term that refers to a state of low temperature, often associated with a perceptibly chilly environment or the sensation of being cool to the touch. Scientifically, cold is relative to the presence and movement of heat, which is a measure of energy within matter. In everyday terms, we experience cold through weather changes, such as during winter months, and it can also be described in the context of specific temperature ranges – for example, temperatures below 32 degrees Fahrenheit (0 degrees Celsius) generally signify freezing conditions, which can impact outdoor activities, personal comfort, and various ecological systems.
Moreover, the sensation of cold is not solely dependent on temperature; factors like humidity and wind chill can enhance the feeling of coldness. When discussing cold in terms of human health, prolonged exposure to cold conditions can lead to hypothermia or frostbite if body heat is not effectively maintained. Hence, it's crucial to dress appropriately and take necessary precautions during colder months to prevent adverse effects. Understanding the concept of cold can help individuals better prepare for seasonal changes and ensure their comfort and safety.
Elderberry (Sambucus) refers to a genus of flowering plants in the family Adoxaceae, comprising several species known for their small berries and traditional medicinal uses. The most commonly recognized species is the European elder, Sambucus nigra, which has been utilized in folk medicine for centuries due to its rich nutrient profile, including antioxidants, vitamins A and C, and dietary fiber. Elderberries are typically fragrant clusters of small, dark purple to black berries that are used in a variety of culinary applications, such as jams, syrups, and wine.
In recent years, elderberry has gained popularity for its potential health benefits, particularly for supporting immune health. Many people consume elderberry supplements or syrups to help alleviate symptoms of colds and flu, with some studies suggesting they may reduce the duration and severity of viral infections.

We explored the effects of vitamin C on the common cold and pneumonia by examining a range of studies. Interestingly, research on animals suggests that vitamin C may have protective effects against infections. However, when it comes to preventing colds in the general population, taking more than 1 gram of vitamin C per day didn’t show significant benefits.
But there's a twist! Participants engaged in heavy physical activities saw their cold incidence reduced by half with vitamin C supplementation. Additionally, regular intake of 1 gram or more daily was linked to a 15% decrease in cold severity. While some therapeutic trials showed inconsistent results when vitamin C was taken after cold symptoms appeared, two studies did indicate that larger doses (6-8 grams per day) could effectively shorten the duration of colds compared to lower doses.
Our investigation also looked into pneumonia, but the studies were conducted in unique settings, such as a boarding school and military recruits. This makes it hard to generalize the findings to the wider population. Yet, some trials suggested benefits for pneumonia patients. Finally, the role of vitamin C in treating COVID-19 and sepsis remains unclear, with mixed results.
Given that vitamin C seems to alleviate symptoms and shorten the duration of colds, while being safe and affordable, it might be worth considering a dose of 6-8 grams per day to see if it helps at an individual level.
