Effects of herbal formula on allergies

Allergies details

Kobayashi H, Mizuno N, Teramae H, Kutsuna H, Ueoku S, et al. The effects of Hochu-ekki-to in patients with atopic dermatitis resistant to conventional treatment. Int J Tissue React. 2004;26:113.

We investigated the effects of Hochu-ekki-to, a traditional Japanese herbal formula that includes astragalus root, on patients struggling with atopic dermatitis who were resistant to conventional treatments.

The treatment consisted of administering this herbal formula for three months, during which we monitored changes in specific markers associated with allergies, namely serum IgE levels and eosinophils, which are key indicators of allergic responses.

Following the treatment, we observed a statistically significant reduction in eosinophil counts, suggesting that Hochu-ekki-to may help alleviate some allergy-related symptoms. Additionally, serum IgE levels showed a slight tendency to decrease, which hints at a potential positive effect on allergies.

It’s important to note that while these findings are promising, the multi-ingredient nature of Hochu-ekki-to makes it difficult to pinpoint exactly how much astragalus root contributes to the overall efficacy. Thus, while we found improvements, it’s challenging to isolate the effects of each ingredient, including the astragalus root.

This product is a fantastic value. Astragalus supports blood pressure and blood sugar—both of which I need—but I mainly buy it for immune support due to my allergies, as I was often falling ill. My mother suffers from severe allergies, and this product alleviates her symptoms effectively. If you find this review helpful, please consider a thumbs up!

Very Strong Astragalus has been highly beneficial for my cirrhosis, effectively supporting my immune system and detoxifying my liver. It has also bolstered my adrenal glands, which in turn supports my thyroid. Strengthening the adrenal glands is crucial, as they produce the hormones required for thyroid function.

Astragaloside IV benefits diabetic nephropathy

Fan Y, Fan H, Li P, Liu Q, Huang L, et al. Mitogen-activating protein kinase kinase kinase kinase-3, inhibited by Astragaloside IV through H3 lysine 4 monomethylation, promotes the progression of diabetic nephropathy by inducing apoptosis. Bioengineered. 2022;13:11517. doi:10.1080/21655979.2022.2068822

We explored how astragaloside IV (AS-IV), a natural compound from the Astragalus root, impacts diabetic nephropathy (DN) and its symptoms. In our observations, AS-IV treatment showed promise in alleviating DN symptoms in mice, leading to improvements in several health markers, including body weight and kidney function indicators such as urine microalbumin and serum creatinine levels.

We noted that AS-IV seemed to reduce the progression of DN by lowering apoptosis, the process of programmed cell death that often contributes to kidney issues in diabetes. Our research revealed that AS-IV affects specific epigenetic modifications, particularly H3 lysine 4 monomethylation (H3K4me1), a mechanism tied to gene expression regulation.

Through our analyses, we pinpointed a gene, MAP4K3, which was elevated in DN conditions but decreased following AS-IV treatment. Silencing this gene led to reduced cell death in kidney cells exposed to high glucose levels, indicating that AS-IV might counteract the harmful effects of diabetes on kidney health. Overall, our findings suggest that AS-IV could play a significant role in protecting against diabetes-related kidney damage, offering a hopeful avenue for future therapies in diabetic nephropathy.

Astragaloside IV lowers H1N1 inflammation

Zhang J, Zhang W, Ren L, He Y, Mei Z, et al. Astragaloside IV attenuates IL-1β secretion by enhancing autophagy in H1N1 infection. FEMS Microbiol Lett. 2020;367. doi:10.1093/femsle/fnaa007

We investigated the effects of astragalus root, specifically a compound known as astragaloside IV (AS-IV), on H1N1 infection, which can cause severe respiratory issues. The key focus was on how AS-IV impacts autophagy, a process cells use to manage inflammation.

In our findings, AS-IV enhanced the formation of autophagosomes, cell structures that help clean up trash within cells, in the context of H1N1 infection. This was significant because H1N1 often leads to an overwhelming release of inflammatory substances, known as a cytokine storm, which can worsen pneumonia symptoms. Surprisingly, while AS-IV didn't impact viral replication or levels of pro-inflammatory proteins, it did significantly lower the secretion of interleukin-1 beta (IL-1β), a key inflammatory marker.

Overall, our study suggests that AS-IV could be helpful in reducing harmful inflammation during H1N1 infection, promoting autophagy activation as a potential avenue for treatment. However, it's crucial to note that the research did not isolate AS-IV's effectiveness specifically as a flu treatment. This leaves some questions remaining about its overall impact on flu symptoms.

Good Immunity Booster. My family has found this to be a good immunity booster during cold seasons. It was particularly beneficial for me while undergoing chemotherapy, as it considerably reduced my white blood count and I needed something to bolster my immunity. I have also heard that it helps protect the liver from the toxic effects of chemotherapy. It has worked very well for us, and we always keep a supply on hand.
