We examined the effectiveness of garlic as a treatment to prevent cold symptoms based on a comprehensive review of systematic reviews. This analysis included various studies that compared garlic and other preventative interventions against a control group receiving no treatment or a placebo.
Our findings indicated that garlic demonstrated notable advantages in reducing instances of influenza, a key player in the spectrum of cold-like illnesses. However, we also learned that the evidence surrounding garlic specifically for cold prevention isn't robust enough to make definitive claims.
It's essential to note that while garlic showed potential, vitamin C did not present any significant benefits in this context. Ultimately, the effectiveness of other interventions remains to be convincingly validated with strong scientific evidence.

Garlic improves cold-induced circulation
In our exploration of how garlic affects circulation during cold exposure, we investigated the specific sulfur compound, -1-propenylcysteine, found in aged garlic extract (AGE). Our study examined how this compound could help alleviate the reduction in blood flow when rats were exposed to cold water.
We conducted a series of tests using Wistar rats subjected to a cold treatment after being administered AGE or its individual components, including -1-propenylcysteine, -allylcysteine, and -allylmercaptocysteine. The results revealed that both AGE and -1-propenylcysteine effectively improved blood flow in the rats' tails, especially at a certain dose of -1-propenylcysteine.
Notably, we found that the improvement in blood flow could be linked to a boost in certain blood components and enzymes related to blood circulation. These findings suggest that -1-propenylcysteine plays a significant role in enhancing blood flow during cold exposure by activating specific pathways in the body.
Our research indicates that while garlic components, particularly -1-propenylcysteine, have the potential to benefit circulation in cold conditions, larger studies are needed to fully understand the implications for human health.

We explored the potential of combining garlic oil with acyclovir (ACV) to tackle the challenges of cold sores caused by the herpes simplex virus. By creating a unique nanoemulsion delivery system, we aimed to enhance how effective ACV is in treating these annoying outbreaks.
Our work involved developing a garlic oil-acylcovir nanoemulsion, which we then incorporated into a transdermal film. This innovative approach was put to the test for its ability to improve skin absorption of the medication. The results were quite promising, showing that our formulation significantly increased ACV's effectiveness compared to regular transdermal methods. We observed a remarkable 2.3 times increase in the absorption of ACV when combined with garlic oil, indicating that garlic may indeed amplify its therapeutic benefits.
However, while this study shows that garlic oil can enhance the performance of acyclovir, we must note that the isolated effects of garlic on cold sores cannot be fully established, as it was tested alongside ACV. Overall, our findings suggest that the garlic oil-ACV blend does make strides toward more effective treatment options for cold sores, paving the way for future explorations in this area of research.

Excellent cold prevention
5 people found this helpful
Best garlic supplement. After trying several, I return to this one due to its lack of taste or smell, and I can tell it works best for my body and immunity. I use it as a preventative for cold/flu and haven't been sick in three years. Combined with Vitamin C and B Complex, plus powdered Colostrum during cold seasons, I recently felt a flu coming and took 2 pills three times a day, and it was gone within 3 days. I never progressed beyond the initial "I'm getting sick" feeling.

Prevents serious illness
4 people found this helpful
An elixir of longevity with a thousand-year history of use. You can list the beneficial properties of garlic for a very long time, but the main obstacle for me has always been its smell, until I discovered this drug. The result for my husband has been a decrease in elevated cholesterol levels to the upper limit of normal and the normalisation of blood pressure after about 5.5 months. A significant "side" effect is that no one in our family has been seriously ill with viral infections or colds during the year of using this drug. If someone did fall ill, the illness passed quickly and easily. Undoubted effects and benefits! The manufacturer is reputable, so I have no desire to switch to cheaper alternatives, hence we stock up on large packages for future use.

This is a great product with no garlic aftertaste that helps a lot when I have a cold.

Less likely to catch cold
I have been using Kyolic's aged garlic extract since the start of this year. The simplicity of this type is great. Though it has a unique garlic smell, it’s not too strong. I believe combining it with vitamin B has boosted my immunity, making me less likely to catch a cold.

No seasonal cold
I use this to combat higher TMAO levels after taking high doses of Choline Bitartrate. Since starting this product, I haven't caught the seasonal cold.
