This study aimed to investigate the acute and subacute oral toxicity of GCXXD in Sprague-Dawley rats. In the acute toxicity study, rats were orally administered 10\u00a0g\/kg GCXXD three times a day. Clinical signs of abnormality and mortality were observed daily for 14\u00a0days. In the subacute toxicity study, rats were orally administered 0, 1.47, 3.83, or 10\u00a0g\/kg GCXXD for 28\u00a0days. The rats\u2019 clinical signs, body weight, food consumption, hematological and biochemical parameters, bone marrow smear, organ index, and pathological morphology were analyzed. The acute toxicity study showed that GCXXD is safe in rats without any obvious toxicity <jats:italic>via<\/jats:italic> an oral dose of 30\u00a0g\/kg\/day (3 \u00d7 10\u00a0g\/kg). After 28\u00a0days of administration, slightly decreased RBC, HGB, and HCT were observed in female rats at 10\u00a0g\/kg, suggesting that repeated doses of high-dose GCXXD may cause mild anemia in female rats. The no-observed-adverse-effect level (NOAEL) and lowest-observed-adverse-effect level (LOAEL) of oral administration of GCXXD for 28\u00a0days in rats are considered to be 3.83\u00a0g\/kg and 10\u00a0g\/kg, respectively. Long-term toxicity studies are recommended to strengthen the findings.<\/jats:p>","DOI":"10.3389\/fphar.2022.1078665","type":"journal-article","created":{"date-parts":[[2023,1,11]],"date-time":"2023-01-11T07:03:02Z","timestamp":1673420582000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["Acute and subacute oral toxicity assessment of Gancao Xiexin decoction in Sprague-Dawley rats"],"prefix":"10.3389","volume":"13","author":[{"given":"Li","family":"Ru","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruotong","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoyu","family":"Xing","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yueming","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zheng","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiyong","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qin","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianping","family":"Song","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaobo","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,1,10]]},"reference":[{"key":"B1","first-page":"32","article-title":"Analysis on clinical application of Gancao Xiexin decoction","volume":"53","author":"Cai","year":"2022","journal-title":"Jiangxi J.
