In a comprehensive clinical trial, we examined the effectiveness of Echinacea purpurea as a preventative measure against the common cold. This research stands out as the largest of its kind, evaluating both the safety and benefits of Echinacea over a long-term treatment period of four months.
We found that this proprietary extract of Echinacea, known as Echinaforce, proved to be beneficial in several ways. It significantly reduced the total number of cold episodes and the duration of those colds. Additionally, participants required fewer medications to cope with their symptoms, highlighting Echinacea's potential as a natural remedy.
Importantly, the extract showed impressive results, particularly for individuals who often experience recurrent infections. The study also indicated that the more closely individuals followed the recommended protocol, the better the preventive effects. Overall, we feel encouraged by the positive risk-to-benefit ratio of Echinacea purpurea when taken as directed for the common cold.

Echinaforce® shows promise for colds
We explored how Echinaforce®, a standardized extract from the Echinacea purpurea plant, can affect respiratory tract infections, including the common cold. In recent research, this treatment was subjected to a rigorous examination through a randomized, double-blind, placebo-controlled study lasting four months. This methodology is important because it allows for a clear comparison between those receiving the treatment and those receiving a placebo.
During the study, we observed that Echinaforce® exhibits immunomodulatory and broad antiviral effects against various respiratory viruses. Notably, it blocks proteins like Haemagglutinin and Neuraminidase, which are often involved in viral replication. One of the significant advantages of Echinaforce® over traditional antiviral medications, such as Oseltamivir, is that it does not lead to viral resistance.
The findings support the idea that Echinaforce® can enhance immune resistance and offers both long-term and short-term benefits for preventing and treating common cold symptoms. This makes it a promising option for individuals looking for natural ways to boost their immune system and combat viral infections.

We conducted a study to explore the safety and effectiveness of Echinacea purpurea in preventing common cold episodes among 755 healthy participants over four months. Participants were randomly assigned to receive either an extract of Echinacea or a placebo, and they diligently recorded any adverse events or cold-related issues in diaries throughout the study period.
Our findings revealed that Echinacea appears to support cold prevention by reducing the number of cold episodes and the overall days spent unwell. Those who used Echinacea experienced fewer occasions requiring pain relief medications and showed a significant decrease in illness due to virally confirmed colds, especially those caused by enveloped viruses. Notably, participants who followed the treatment protocol closely benefitted the most, showing enhanced preventive effects from Echinacea.
Throughout the study, safety was carefully monitored, revealing that the incidence of adverse events was similar between those taking Echinacea and those on placebo. This indicates that Echinacea has a favorable safety profile comparable to taking no active treatment at all.
Overall, regular intake of Echinacea purpurea can offer a valuable boost in our defenses against the common cold, making it a potential natural remedy for those looking to reduce the frequency and severity of colds.

Highly effective remedy
Effective cold medicine! A really effective remedy. At the first signs of the common cold, I followed the suggested regimen. I managed not to get ill, and after three days, all symptoms vanished as if by magic. I initially bought one jar for a trial, but I’ve now ordered two more. In St. Petersburg, it’s an essential item during off-season! I highly recommend it.

My golden ticket
The best line of defence! As a Canadian, I can't find Gaia in Canada. While in California, I caught a sore throat and bought these at a health food store. I took them enthusiastically—10 a day at onset—and they worked brilliantly. I've been having them shipped ever since, especially with flu season approaching, along with Allimax at the first signs of a common cold; it's my golden ticket!

Stronger than alternatives
Quick Defence works! I recently tried Gaia Herbs Quick Defence with fantastic results. After taking it for two days (40 caps) to address strong viral symptoms resembling a cold/flu, I felt fine on the third day. Previously, I used Gaia Herbs echinacea, but Quick Defence proved more effective, and the dosing was straightforward. I will keep it handy.

We're diving into the effectiveness of Echinacea for children dealing with acute cold and flu symptoms. A total of 79 children, aged between 4 and 12, were included in this study. We randomized them to receive either three or five doses of Echinaforce Junior tablets daily, allowing us to compare the benefits of 1200 mg versus 2000 mg of Echinacea extract.
During the cold episodes, parents diligently recorded their child's respiratory symptoms, while both parents and physicians provided feedback on how well the treatment was tolerated. Our observations revealed that Echinacea was well-received, boasting an impressive tolerability rate of over 96%. On average, cold episodes lasted 7.5 days, and most children fully recovered within 10 days.
Notably, we found that those taking five doses of Echinacea daily experienced a shorter average duration of symptoms, cutting the episode time by about 1.7 days compared to those taking three doses. This effective symptom relief led to low antibiotic prescriptions, with only 4.6% of children needing them. Overall, we see Echinacea tablets as a promising option for managing acute cold episodes in children, especially at higher doses.

In our study, we investigated the effectiveness of a multiherbal formula called Immumax, which includes Echinacea, alongside garlic, Nigella sativa oil, Panax ginseng, vitamin C, and zinc, in treating the common cold. Conducted in an outpatient setting, this double-blind, randomized, controlled trial involved 62 participants who exhibited common cold symptoms. They were divided into two groups; one received Immumax, while the other received a placebo.
Our findings revealed that the patients taking Immumax experienced a significant reduction in the duration and severity of their cold symptoms compared to those on the placebo. Specifically, the average time for symptoms to resolve was notably quicker—4 days for Immumax users versus 8 days for the placebo group. Additionally, by day four and eight, there was a significant decrease in overall symptom severity scores among Immumax recipients.
Overall, we can confidently say that the inclusion of Echinacea in the multiherbal formula contributes positively to managing cold symptoms, aiding in quicker recovery. However, it’s essential to note that we didn't isolate the individual effects of Echinacea, so while it seems beneficial within this combination, we can’t definitively attribute all the positive effects solely to Echinacea.

We explored the effects of specific compounds called alkylamides, found in a medicinal herb, on common cold symptoms. Our study focused on the antiviral and inflammatory responses of these alkylamides, particularly how they interact with respiratory viruses like rhinovirus and influenza.
We found that one alkylamide, Dodeca-2,4-Dienoic acid isobutylamide, was particularly effective. It showed a strong ability to inhibit the replication of these viruses while also reducing the production of a specific cytokine called IL-8. High levels of IL-8 are linked to many cold symptoms and other respiratory infections.
The promising results, along with low toxicity, suggest that this alkylamide could be a useful treatment for those suffering from colds or flu. Overall, our findings highlight the potential benefits of alkylamides in alleviating cold symptoms and promoting better respiratory health.
