Ethnopharmacological relevance Spermatogenic Pill (SP) is a commonly used clinical preparation in the Third Clinical Hospital of Changchun University of Traditional Chinese Medicine. Has accumulated a good reputation for more than a decade. However, because SP is a hospital clinical agent, it has received little extensive attention from researchers, which has led to a systematic lack of basic research on it. Therefore, it is impossible to determine whether there are safety hazards that may limit its widespread clinical application, and an in-depth toxicological evaluation of SP is essential and urgent. Aim of the study The aim of this study was to assess the safety of SP by conducting acute and subacute toxicity examinations. Materials and methods Identify active compounds contained in SP by LC-MS, and determination of inorganic elements in SP using ICP-MS. The in vivo acute toxicity of SP was assessed over a duration of 14 days following administration at doses of 7.5, 15, or 30 g/kg. To evaluate subacute toxicity, mice were administered daily doses of SP (7.5, 15, or 30 g/kg) for a period of 28 days. After the treatment period, the animals were euthanized, and standard blood tests, liver and kidney function tests, as well as tests related to glycolipid metabolism, were performed. The principal organs of the mice were collected to calculate organ coefficients and undergo hematoxylin-eosin (HE) staining. Results LC-MS analysis showed that the active components of SP include Quercetin, Kaempferol, Beta-sitosterol, Stigmasterol, Diosbulbin B, Schizandrin, Naringenin, 2,3-hydroxycinnamic acid, L-proline, Histidine and Pluviatolide. The total amount of detected inorganic elements accounted for 3.0919% of SP. During the SP acute toxicity experiment, the groups that received the drug exhibited no signs of adverse reactions or poisoning symptoms. In subacute toxicity experiments, drug-treated mice showed overall favorable status, but the effects of continuous administration of the 30 g/kg group on body weight and food intake were reduced. An increase in the white marrow of spleen tissue after long-term administration of the drug treatment was also observed, suggesting that the drug can increase the maturation process and the number of mature lymphocytes in the spleen, and improve the lymphocyte immunity and humoral immunity function of the organism. Suggests that possibly this should be taken into account in clinical application. The routine blood examinations, as well as the assessments of liver and kidney functions, and the tests for glucose and lipid metabolism, did not reveal any notable toxic effects. Conclusion SP contains more flavonoids, and terpenoid active ingredients, and is non-toxic in the body. This discovery not only strengthens the safety foundation of its clinical application, provides a solid scientific basis for the establishment of reasonable clinical dosage and the implementation of effective clinical toxicity monitoring, but also further lays a solid theoretical cornerstone for the subsequent clinical drug trials.
