Scutellaria Baicalensis Root Extract

Also known as: Scutellaria baicalensis Georgi, Baikal skullcap, Chinese skullcap, Huang-qin, Scutellaria baicalensis

Overview

Scutellaria baicalensis, also known as Baikal skullcap or Huang-qin, is a plant native to China and Russia. Its root has been used in traditional Chinese medicine for centuries due to its purported health benefits. The root extract contains bioactive compounds such as baicalin, baicalein, and wogonin, which are believed to be responsible for its pharmacological effects. Traditionally, it has been used for fever clearance, detoxification, and inflammation reduction. Modern research is exploring its potential in treating conditions such as depression, cancer, and inflammation. While research is ongoing, the quality of evidence varies, with preclinical studies showing promising results, but more rigorous clinical trials are needed to fully understand its effects in humans. It is available in various forms, including dried root, extracts, and capsules.

Benefits

Scutellaria baicalensis has shown potential benefits in several areas, primarily supported by preclinical studies. A systematic review and meta-analysis of animal models suggests that it can alleviate depressive behaviors, with significant effects observed in behavioral tests such as the SPT, OFT, and NSFT. Preclinical studies also indicate anti-tumor and anti-angiogenic effects, particularly in hepatocellular carcinoma and lung cancer models. Additionally, anti-inflammatory and anti-oxidative effects have been reported, though these are less extensively studied in humans. While these findings are promising, human studies are limited, and the clinical significance of these benefits remains to be fully established. More high-quality clinical trials are needed to confirm these effects in humans.

How it works

Scutellaria baicalensis exerts its effects through several biological pathways. Its neuroprotective and antidepressant effects are thought to involve the modulation of neurotransmitter systems and the reduction of neuroinflammation in the central nervous system. In cancer cells, it inhibits cell proliferation, induces apoptosis, and exhibits anti-angiogenic properties, potentially through targeting STAT3. The active compounds interact with the immune system to reduce inflammation. However, the bioavailability of compounds like baicalin is generally low due to extensive first-pass metabolism, which affects its overall efficacy. Further research is needed to fully elucidate the mechanisms of action and improve bioavailability.

Side effects

Scutellaria baicalensis is generally considered safe when used appropriately, but more data on long-term use are needed. Common side effects, occurring in more than 5% of users, include gastrointestinal upset. Uncommon side effects, affecting 1-5% of users, may include allergic reactions. Rare side effects, seen in less than 1% of users, can include severe allergic reactions. It may interact with blood thinners and diabetes medications, potentially affecting their efficacy. It is contraindicated in pregnancy and breastfeeding due to a lack of safety data. Caution is advised in patients with bleeding disorders or those taking anticoagulants. It is important to monitor for any adverse effects and consult a healthcare provider if they occur.

Dosage

The optimal dosage of Scutellaria baicalensis is not well-established for most conditions. Typically, a dosage of 1-3 grams of dried root per day is used. The maximum safe dose is not clearly defined, and caution is advised beyond 3 grams per day. There are no specific timing recommendations for its use. Extracts may be more bioavailable than the raw herb. Bioavailability can be enhanced with certain formulations. It is important to consult with a healthcare provider to determine the appropriate dosage for individual needs and to monitor for any potential side effects. No specific cofactors are required for its use.

https://pubmed.ncbi.nlm.nih.gov/38572433/ – This systematic review and meta-analysis, encompassing 13 studies in animal models, investigates the antidepressant effects of Scutellaria baicalensis. The findings suggest that S. baicalensis exhibits significant antidepressant effects in animal models, indicating its potential as a therapeutic agent for depression. However, the study is limited to preclinical data, and there is a moderate risk of bias due to heterogeneity among the included studies.
https://pmc.ncbi.nlm.nih.gov/articles/PMC10795786/ – This preclinical study explores the anti-tumor and anti-angiogenic effects of Scutellaria baicalensis in various cell lines and animal models. The results demonstrate that S. baicalensis has promising anti-cancer properties, particularly in hepatocellular carcinoma and lung cancer models. While the preclinical data is high-quality, human clinical trials are necessary to validate these findings.
https://www.mdpi.com/1422-0067/22/10/5181 – This in vitro study examines the effects of Scutellaria baicalensis on human lung cancer cell lines. The study found that S. baicalensis induces apoptosis in EGFR TKI-resistant lung cancer cells, suggesting its potential as a therapeutic agent for lung cancer. However, the findings are limited to cell culture models and require in vivo and clinical validation.
https://pubmed.ncbi.nlm.nih.gov/36902160/ – This study investigates the impact of Scutellaria baicalensis on multidrug resistance in hepatocellular carcinoma (HCC) cells. The research indicates that baicalein, a compound found in S. baicalensis, can reverse multidrug resistance in HCC cells by inhibiting P-glycoprotein expression. This suggests a potential therapeutic strategy for overcoming drug resistance in liver cancer treatment.
https://www.tandfonline.com/doi/full/10.1080/07853890.2023.2247004 – This study explores the synergistic effects of Scutellaria baicalensis and Sophora flavescens extracts on atopic dermatitis (AD)-like skin lesions in mice. The results demonstrate that the combination of these extracts significantly alleviates AD-like symptoms by reducing inflammation and improving skin barrier function. This suggests a potential natural therapeutic approach for managing atopic dermatitis.
