Differences in cultivation, harvesting, and processing methods can affect the consistency and potency of the final product. Recent updates in regulations aim to address these issues by implementing stricter quality control standards and requiring more rigorous clinical evidence. For example, the EMA has introduced new guidelines for the standardization of herbal medicinal products to ensure consistent quality and safety (Knöss, 2018). Regulatory frameworks for aromatic medicinal plants differ globally. In the United States, the FDA's approach focuses on post-market surveillance and consumer safety, while the EMA in the European Union emphasizes pre-market evaluation and approval (Qu et al., 2018; Sarma et al., 2021). In Asia, countries like China and India have their traditional medicine systems integrated with modern regulatory practices. China's State Administration for Market Regulation (SAMR) and India's Ministry of AYUSH regulate the use of herbal medicines, ensuring they meet safety and efficacy standards (Seethapathy et al., 2019; Nirmal et al., 2022). Comparing these frameworks highlights the need for international harmonization to facilitate global trade and ensure consumer safety. 7.3 Risk assessment and management Risk assessment of aromatic medicinal plants involves identifying potential hazards, evaluating exposure levels, and determining the likelihood of adverse effects. Methods include toxicological testing, clinical trials, and post-market surveillance. Toxicological testing in preclinical studies assesses acute, subacute, and chronic toxicity (Pande et al., 2018; Sorokina et al., 2019). Clinical trials provide data on safety and efficacy in humans, while post-market surveillance monitors adverse events and ensures ongoing safety. Effective risk management strategies involve implementing safety guidelines, educating consumers, and monitoring product use. Safety guidelines include recommended dosages, contraindications, and potential side effects. Educating consumers about the proper use of these plants and their products is crucial for preventing misuse and adverse effects. Monitoring product use through adverse event reporting systems helps identify emerging safety concerns and allows for timely intervention. Case studies highlight the practical application of risk assessment and management strategies. The safety evaluation of tea tree oil involved extensive preclinical testing and clinical trials to assess its dermatological effects (Martínez Campayo et al., 2020). Risk management strategies included labeling requirements to inform consumers about potential allergic reactions. Another case study on the use of eucalyptus oil in respiratory therapies demonstrated the importance of dose regulation and monitoring for adverse effects, leading to the development of standardized dosing guidelines to ensure safe use. 8 Case Study: Syzygium aromaticum 8.1 Overview of Syzygium aromaticum Syzygium aromaticum, commonly known as clove, is a highly aromatic plant native to the Maluku Islands in Indonesia. It is now also cultivated in other tropical regions such as China, Madagascar, India, Sri Lanka (Chniguir et al., 2019). The plant is characterized by its fragrant flower buds, which are harvested and dried to produce the spice known as clove. Clove trees can grow up to 20 meters tall and have large, glossy leaves and clusters of small, red flowers. The plant is known for its rich content of essential oils and bioactive compounds, which contribute to its diverse pharmacological properties (Chniguir et al., 2019; Xue et al., 2022). Clove has a long history of use in traditional medicine and culinary practices. In traditional Chinese medicine (TCM) and Ayurveda, clove has been used to treat digestive issues, toothaches, and respiratory conditions. The spice was highly valued in ancient trade routes and was a significant part of early global commerce. Historically, clove was also used as a preservative due to its antimicrobial properties, and it played a role in various cultural rituals and traditional health practices.
