Bronchitis details

Garlic extract inhibits IBV effectively

Mohajer Shojai T, Ghalyanchi Langeroudi A, Karimi V, Barin A, Sadri N. The effect of Allium sativum (Garlic) extract on infectious bronchitis virus in specific pathogen free embryonic egg. Avicenna J Phytomed. 2016;6:458.

We set out to understand the potential of garlic extract in combating the infectious bronchitis virus (IBV), which can cause significant health issues in chickens. The study involved specific pathogen-free embryonic eggs, separated into four groups. These groups were used to analyze the effects of various concentrations of garlic extract on the virus and determine if it could help reduce the impact of IBV.

During our research, we utilized gas chromatography to identify the constituents of the garlic extract. The first group of eggs was used to determine the virus's potency. The second group received a mix of the virus and a steady amount of garlic extract, while the third group got a delayed garlic extract treatment. Finally, the last group was treated with different dilutions of garlic extract alone.

The results were promising: we found that garlic extract did indeed have inhibitory effects on IBV in chicken embryos. Particularly in the second and third groups, there was a notable increase in the embryonic index, indicating that the garlic extract positively influenced the embryos' response to the virus.

These findings suggest that garlic extract could be a valuable natural remedy against IBV, especially in the face of emerging vaccine-resistant strains. Thus, garlic may not only serve as a culinary ingredient but also as a potential therapeutic agent in veterinary medicine.

We explored the potential benefits of a garlic-derived compound called diallyl trisulfide (DATS) in combating the H9N2 avian influenza virus. This study specifically looked at its antiviral properties both in human cells and in mice to see if it could provide relief from this infection.

In our research, we treated human lung A549 cells and also utilized BABL/c mice to assess DATS’s effectiveness. We applied DATS before and after the infection and measured its impact on viral loads, inflammatory responses, and overall lung health.

The results were promising. Whether given before or after exposure to the virus, DATS treatment reduced viral loads and led to an improved immune response by increasing antiviral gene expression while also decreasing inflammatory cytokines. Similar benefits were observed in infected mice, highlighting less lung inflammation and edema.

Overall, the findings suggest that DATS may offer a novel alternative for treating influenza, specifically the H9N2 strain, showcasing garlic's potential role in managing viral infections.

Allergies details

Garlic compounds reduce allergy symptoms

Kim JE, Budluang P, Park J, Lee KH, Pakdeepromma S, et al. N-benzyl-N-methyldecan-1-amine, derived from garlic, and its derivative alleviate 2,4-dinitrochlorobenzene-induced atopic dermatitis-like skin lesions in mice. Sci Rep. 2024;14:6776. doi:10.1038/s41598-024-56496-2

We explored the use of two compounds derived from garlic, N-benzyl-N-methyldecan-1-amine (BMDA) and its derivative, in addressing atopic dermatitis (AD) symptoms in mice. The study focused on whether these garlic-based treatments could alleviate skin lesions induced by a known irritant, 2,4-dinitrochlorobenzene (DNCB).

Our findings showed that topical application of BMDA and its derivative significantly reduced swelling, redness, and scratching associated with AD-like conditions. We noticed a remarkable decrease in skin inflammation and a reduction in the number of mast cells, which play a key role in allergic responses. Notably, the treatments also lowered IgE levels, a marker often related to allergic reactions, suggesting that these compounds could affect the underlying allergic response.

Furthermore, by analyzing skin samples, we found that the garlic-derived compounds decreased the levels of several inflammatory cytokines that typically drive allergic reactions. This extended to major inflammation-related signaling molecules, indicating that the treatment helped calm the overactive immune response often seen in allergic conditions like AD.

Overall, our research suggests that BMDA and DMMA have potential as novel treatments for managing inflammatory responses associated with allergies, particularly atopic dermatitis. This is exciting because it opens the door to new, plant-based approaches for allergy treatment while emphasizing the health benefits of garlic and its derivatives.

Garlic inhibits B. hominis growth

We embarked on a study to investigate how garlic, alongside other natural substances, affects the growth of Blastocystis hominis in patients suffering from irritable bowel syndrome (IBS). Our research included stool specimens from both IBS patients and healthy controls to compare their responses to metronidazole (MTZ) and dietary spices like garlic.

As we explored our findings, we discovered that garlic had a significant impact, especially at lower concentrations. Specifically, over half of the B. hominis samples from IBS patients didn’t grow when exposed to garlic at a concentration of 0.01 mg/ml. As we increased the concentration to 0.1 mg/ml, the results were similarly promising, with a notable decrease in cell counts indicating that garlic can effectively inhibit the growth of this parasite in IBS patients.

Although garlic showed effectiveness, it's worth mentioning that some patients showed different responses compared to the healthy controls. For instance, while garlic reduced the B. hominis cell count in IBS patients, the control group experienced no growth of the parasite at the same concentrations. This suggests that the IBS condition may affect how well the garlic works.

Overall, while garlic indicates potential benefits for those battling IBS and Blastocystis hominis, we should also consider further research to fully understand its effectiveness and the nuances of its action in different individuals.

Liu Y, Nie M, Li X, Wang H, Ren S, et al. Garlic-derived Exosomes Alleviate Osteoarthritis Through Inhibiting the MAPK Signaling Pathway. Appl Biochem Biotechnol. 2025;197:518. doi:10.1007/s12010-024-05047-6

In our exploration of garlic's potential benefits for arthritis, we focused on a type of tiny particle called garlic-derived exosomes (GDEs). These particles come from garlic and have shown promise in reducing inflammation in various health issues. We specifically examined how they affect osteoarthritis (OA), a condition that impacts millions by causing joint pain and stiffness.

Our study involved both laboratory and animal models. We treated chondrocytes, the cells in cartilage, with a pro-inflammatory substance while exposing them to GDEs. We found that the garlic-derived particles helped to boost the levels of beneficial cartilage components while inhibiting harmful enzymes that break down cartilage. Additionally, GDEs appeared to reduce the activity of key signaling pathways related to inflammation.

On the animal side, we used a surgical model to simulate OA and injected GDEs directly into the knee joints of mice. The results were encouraging; the GDEs alleviated pain and improved how the mice moved. Histological examinations revealed less joint destruction, suggesting that these garlic particles could indeed help slow the progression of OA without causing toxicity.

Overall, our findings indicate that garlic-derived exosomes hold potential as a treatment for osteoarthritis, making it a significant area for future research into disease-modifying therapies.
