Medicinal Plant Research 2024, Vol.14, No.3, 162-170 http://hortherbpublisher.com/index.php/mpr 167 use of Alchemilla vulgaris in wound healing has been validated through in vitro and in vivo studies, demonstrating its efficacy in promoting skin repair (Tasić-Kostov et al., 2019). This convergence of traditional knowledge and modern science underscores the enduring value of these medicinal plants and highlights the importance of integrating traditional medicine with contemporary healthcare practices. By bridging the gap between historical uses and modern scientific validation, we can better understand the full therapeutic potential of Hydrocotyle vulgaris and related species, paving the way for their incorporation into modern medical treatments. 6 Safety and Toxicity 6.1 Assessment of toxicity levels The assessment of toxicity levels in Hydrocotyle vulgaris has been explored through various studies focusing on its phytochemical properties and potential therapeutic applications. One study investigated the heavy metal content and phytochemical composition of a related species, Hydrocotyle sibthorpioides, and found negligible amounts of toxic elements, suggesting a low toxicity profile for the genus (Swargiary and Daimari, 2021). The study highlighted the plant's potential for safe use in medicinal applications due to its minimal toxic effects and high cell membrane permeability. 6.2 Safe dosage ranges Determining safe dosage ranges for Hydrocotyle vulgaris involves evaluating its physiological responses under different conditions. For instance, a study on the plant's cadmium tolerance revealed that it could grow normally under various cadmium concentrations, indicating a robust tolerance to environmental stressors (Liu et al., 2021). This resilience suggests that Hydrocotyle vulgaris can be safely used within a broad range of dosages without adverse effects. However, specific dosage recommendations for therapeutic use would require further detailed pharmacological studies. 6.3 Long-term safety studies Long-term safety studies are crucial to understanding the chronic effects of Hydrocotyle vulgaris consumption. While there is limited direct research on the long-term safety of Hydrocotyle vulgaris, insights can be drawn from studies on its antioxidant and free radical scavenging activities. For example, research has shown that Hydrocotyle vulgaris possesses significant antioxidant properties, which could mitigate oxidative stress and reduce the risk of long-term toxicity. Moreover, the plant's non-irritating pH levels and good spreadability values further support its potential for safe long-term use in biocosmetic applications (Ureta et al., 2018). Nonetheless, comprehensive long-term studies are necessary to fully establish its safety profile over extended periods. 7 Challenges and Future Directions 7.1 Current research limitations Despite the promising therapeutic potential of Hydrocotyle vulgaris, current research has several limitations. One significant limitation is the lack of comprehensive clinical trials to validate the efficacy and safety of H. vulgaris in human subjects. Most studies, such as those evaluating its antioxidant properties and free radical scavenging activities, have been conducted in vitro or in animal models (Ureta et al., 2018). The variability in extraction methods and phytochemical analysis techniques can lead to inconsistent results, making it difficult to standardize the therapeutic use of H. vulgaris. There is limited information on the long-term effects and potential side effects of H. vulgaris, which is crucial for its integration into modern medicine. 7.2 Potential areas for future study Future research should focus on several key areas to fully realize the therapeutic potential of Hydrocotyle vulgaris. Firstly, conducting well-designed clinical trials is essential to establish the efficacy and safety of H. vulgaris in treating various conditions, particularly those related to oxidative stress and aging. Exploring the plant's potential in phytoremediation, as indicated by its cadmium tolerance and removal efficiency, could open new avenues for environmental applications (Ni et al., 2018; García-Oliveira et al., 2021). Investigating the synergistic effects of H. vulgaris with other medicinal plants or conventional drugs could enhance its therapeutic efficacy. Research should also aim to standardize extraction and analysis methods to ensure consistency and reliability of results across different studies.
