We investigated how Echinacea, a popular herbal remedy known for its immune-boosting properties, affects mice with autoimmune diabetes, specifically using the NOD mouse model that naturally develops Type 1 diabetes. Our focus was on the herb's impact on NK cells—key players in the immune system that are often deficient in this condition.
Through our study, we discovered that feeding Echinacea to these mice resulted in a significant increase in NK cell numbers in both the spleen and the bone marrow. This enhancement occurred regardless of whether the mice received the herb for a short (days) or long (months) period. Additionally, we observed early changes in other immune cell types, suggesting that Echinacea has an immediate, though temporary, effect on immune dynamics.
Importantly, our findings indicate that Echinacea consumption did not lead to any negative effects on the immune or hemopoietic systems in the mice. This consistent increase in NK cells could represent a new avenue for treating Type 1 diabetes, potentially offering a fresh approach to managing this challenging autoimmune disorder.

We’ve had great results with Echinacea Supreme. We've ordered it previously and found it effective. I cannot recommend Echinacea Supreme enough; it genuinely works for me, unlike other cold remedies I've tried.

Echinacea shows promise against influenza
We focused on how echinacea, a well-known wildflower, can combat viruses that commonly cause respiratory infections, specifically influenza A and B, as well as respiratory syncytial virus (RSV). Through a methodical approach, we evaluated the effects of a 60% ethanol extract of echinacea and its active compound, chicoric acid (CA), on these viruses.
Our research utilized various tests to measure the antiviral effectiveness of echinacea. We observed that both the extract and chicoric acid significantly reduced the infectivity of H1N1, IVB, and RSV-A in controlled experiments. Notably, our findings indicated a decrease in viral gene expression and confirmed through microscopy that echinacea's components could limit the ability of these viruses to infect host cells.
Additionally, we found that echinacea's extract and chicoric acid effectively hindered the attachment of H1N1 and IVB viruses to cell receptors, showcasing their potential utility in preventing these viral infections. With this strong set of results, we believe that echinacea could serve as a promising natural remedy or ingredient in functional health foods aimed at reducing the impact of viral respiratory infections.

Very effective for influenza. I have repurchased this product multiple times. My boyfriend recovered quickly after using it for just 1-2 days, which prevented a week-long illness. I recommended it to a friend whose child and husband were infected; it worked wonders for them too. Purple Daisy has now become an essential supplement in my home. When infected, I suggest taking 2 pills every 2 hours and several times daily, especially combined with vitamin C for better results.

We explored how Echinacea purpurea, a plant commonly used in herbal tea, might help relieve allergies by focusing on its effects on mast cells. Mast cells play a significant role in type-I allergies, such as hay fever, by releasing histamine and leukotrienes—substances that cause allergic symptoms.
Our evaluation involved water extracts from the petals, leaves, and stems of Echinacea purpurea. We specifically looked at how these extracts influenced the release of histamine and other chemical mediators from mast cell lines. The results were quite interesting: both petal and leaf extracts significantly reduced histamine release in stimulated cells. However, the stem extract did not show any effect.
Notably, we found that the petal extract was much more effective than the leaf extract. Additionally, all extracts effectively suppressed leukotriene B4 production, which is another mediator involved in allergic reactions. The petal extract also seemed to decrease certain cellular signaling events associated with mast cell activation.
Overall, our findings suggest that Echinacea purpurea petal extract could potentially help alleviate allergic symptoms, particularly in conditions like hay fever.

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.

Echinacea shows flu treatment promise
We explored the effectiveness of Echinaforce Hotdrink, an echinacea-based formulation, against oseltamivir, a standard flu treatment. In a randomized, double-blind trial involving 473 patients with early flu symptoms, we found that both treatments led to similar recovery rates.
Echinaforce showed a promising profile with fewer complications and side effects, making it an appealing option for those looking for self-care alternatives in flu treatment. This study sheds light on the potential of echinacea as a viable treatment for influenza.

Very useful for influenza. I have repurchased this numerous times. My boyfriend recovered swiftly from the flu after taking it for just 1-2 days. Without it, he would have been ill for a week. I also introduced this supplement to a friend whose family was infected; it proved very effective. Purple Daisy has become a staple in my home. During an infection, it's best to take 2 pills every 2 hours and several times a day, preferably with vitamin C for enhanced efficacy.
