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.

Excellent! Organic elderberry gummies are easy to take. Consume them at the onset of a cold, and you’ll be cured within a day.
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.

Essential for colds
Black elderberry is indispensable in our household during cold season. It improves metabolism and strengthens immunity thanks to its high vitamin content. Packed with essential nutrients, it’s a product I highly recommend. Thank you iHerb for this fantastic product.
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. However, it’s important to note that raw elderberries, as well as other parts of the elderberry plant, can be toxic if consumed in large amounts. Therefore, it's recommended to use elderberry products that are properly processed and prepared to ensure safety and efficacy.
Elderberry, specifically the Sambucus variety, has garnered attention for its potential benefits in alleviating cold symptoms. Research suggests that elderberry extract may shorten the duration of flu and cold symptoms, as it appears to enhance immune response and inhibit viral replication. Many studies indicate that those taking elderberry supplements experienced a reduction in the severity and duration of cold symptoms when compared to a placebo. This is largely attributed to the antioxidants, vitamins, and other compounds found in elderberries, which can help bolster the health of the immune system.
However, it’s essential to approach elderberry with caution. Not all elderberry products are created equal; some may contain added sugars or fillers that dilute their efficacy. Additionally, elderberry should not be used as a substitute for professional medical advice or treatment, especially for severe illnesses. While it can be a helpful addition to your health regimen during cold and flu season, it's best to consult with a healthcare provider for personalized recommendations.
Based on user reviews, results from taking elderberry gummy supplements for cold symptoms can be seen quite rapidly, particularly if taken at the onset of symptoms. Many users report noticeable improvements within a day or two. For example, one user stated that they were "cured within a day" of taking the gummies when they first felt symptoms Read Review. Other reviews suggest that symptoms often resolve within two to four days when the gummies are taken at the first signs of a cold Read Review, Read Review.
Overall, it appears that the quicker you start the supplement when cold symptoms appear, the sooner you can expect to see results.

Vitamin C has garnered significant attention in relation to cold prevention and treatment, with several studies suggesting it may offer some benefits. While descriptive animal studies indicate that vitamin C could provide protective effects against infections, its efficacy in preventing colds for the general population remains limited. Research shows that exceeding 1 gram of vitamin C daily does not significantly reduce the incidence of colds. Conversely, participants engaged in heavy physical activities experienced about a 50% reduction in cold occurrence with higher doses, and regular intake of 1 gram or more correlates with a 15% decrease in cold severity. Interestingly, larger doses taken at the onset of symptoms may shorten the duration of colds, making it potentially useful for individuals looking for relief [1].
On the other hand, elderberry has shown more promise as a natural remedy for cold symptoms. Various clinical trials indicate that taking elderberry may significantly alleviate the severity and duration of cold symptoms, with participants reporting about 50% symptom relief within just a few days of initiating treatment [7]. Moreover, elderberry seems to be a safe option for managing respiratory conditions, as adverse effects are infrequent [8]. While both vitamin C and elderberry are worth considering for cold management, elderberry appears to have more robust evidence supporting its effectiveness for symptom relief.
Based on user reviews, many individuals have reported significant improvements in their cold symptoms after using elderberry gummy supplements. Users frequently mention that these gummies are especially effective when taken at the onset of symptoms. For instance, one user shared that they felt "cured within a day" after starting the gummies as soon as they felt a cold coming on Read Review. Another user indicated that by taking the gummies every four hours at the first signs of illness, their cold was typically resolved by the second day Read Review.
Several reviewers also highlighted the overall impact on their immune health, citing that regular use of the gummies not only alleviated cold symptoms but also provided a noticeable energy boost and aided in preventing future colds Read Review. Overall, users express high levels of satisfaction, emphasizing a blend of convenience, taste, and effectiveness in addressing cold symptoms and enhancing immunity Read Review. However, it's important to note that individual results may vary, and effectiveness can depend on various factors including timing and overall health.
Users have reported positive experiences when combining elderberry gummy supplements with other vitamins, particularly for managing cold symptoms. For instance, one reviewer highlighted that the effectiveness of the elderberry gummies was significantly enhanced when taken alongside additional supplements like zinc and vitamin C, noting that this combination helped resolve symptoms much quicker than using elderberry alone Read Review. Another user elaborated on their success when using the gummies in conjunction with silver and grapefruit seed extract, which further accentuated the speedy recovery from cold symptoms Read Review.
Overall, consumers frequently express that these gummies serve as an excellent foundation for a multi-supplement approach during cold season, contributing not only to symptom relief but also acting as a preventative measure when dosages are increased at the onset of illness Read Review. Many users appreciate the versatility of the gummies, finding them a pleasant and effective addition to their wellness regimen, particularly in combination with other nutritional support to fortify their immune system Read Review.
Recent research has indicated that elderberry (Sambucus nigra) may be a promising natural remedy for reducing the severity and duration of cold symptoms. In a review of five clinical studies involving approximately 936 adults, participants taking mono-herbal elderberry preparations within the first 48 hours of symptom onset reported about a 50% improvement in their symptoms within 2 to 4 days. This finding suggests that elderberry could be an effective alternative to traditional over-the-counter medications for those experiencing common colds [7]. Furthermore, elderberry supplementation has been shown to significantly ease upper respiratory symptoms, indicating it might be safer and just as effective for individuals seeking relief during viral infections [8].
Although elderberry does not seem to significantly prevent colds, its use may still be beneficial in alleviating the duration and intensity of cold symptoms when they occur. Importantly, no serious side effects have been reported, which contributes to its favorable safety profile. While the optimal dosing of elderberry isn’t explicitly detailed in the studies, the general consensus supports the use of elderberry supplements for symptom relief in a practical and timely manner. For anyone considering elderberry as part of their cold treatment strategy, it's worthwhile to explore further options, keeping in mind that more research is needed to fully establish its effectiveness [6].

Effective for cold
The first suggestion helped me significantly, and the second one is delicious. It worked swiftly at the first sign of a cold, taking only two days in conjunction with other supplements like silver and grapefruit seed extract.
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.

Evaluating elderberry for colds
Elderberry for prevention and treatment of viral respiratory illnesses: a systematic review.
We investigated the potential of elderberry as a treatment to help with cold symptoms. In our review, we looked at several clinical trials that specifically examined elderberry's effectiveness in reducing the severity and duration of cold illnesses.
While elderberry might not significantly lower the risk of catching a cold, we found evidence suggesting it could help decrease how long and how severely colds affect us. The data on this was uncertain, though, so we can't say with complete confidence that elderberry is a miracle cure.
Additionally, when comparing elderberry with antiviral medications, such as oseltamivir, there are hints that an elderberry product might lead to fewer complications and side effects for individuals dealing with influenza. It's also worth noting that while elderberry may influence some inflammatory markers, it does not seem to spur excessive immune responses that could lead to negative health outcomes like a “cytokine storm.”
In conclusion, elderberry appears to be a safe option for addressing viral respiratory issues, including colds. However, more research is needed to clearly establish its benefits and any potential downsides.
