“…They found that the leaves of B. juncea and C. intybus in soils spiked with cyanide had the highest Au accumulation at a rate of 326 mg kg −1 (B. juncea) and 164 mg kg −1 (C. intybus). Another study conducted by Vural and Safari [138] evaluated the potential of Helichrysum arenarium for Au accumulation; they reported TF and BAF values of 2.04 and 0.59, respectively. They concluded that enhancing the availability of Au in soil by adding chelators like NaCN, SCN − , and thiosulfates can lead to the usage of Helichrysum arenarium in the PM process.…”

Phytomining (PM) is defined as the process of using plants capable of bio-extracting metals from soil in order to explore them economically. This relatively new, innovative method has been gathering significant attention in both the academic and commercial domains. Conventional mining methods are often economically unviable when applied to lean ores, and they can lead to secondary pollution in soil—a situation that applies to all excavated metals. On the other hand, PM is an environmentally friendly and economically viable solution that addresses the growing demands for metal resources, while simultaneously contributing to energy production by harnessing biomass energy. This comprehensive review presents the current PM techniques, challenges, and the hyperaccumulator plant species that may be used for the extraction of the main targeted elements in the process. Typically, the targeted metals are those of economic value, which can later be deposited or sold to various industries. This review also analyzes the factors influencing the economic viability of PM and proposes potential enhancements. Undeniably, PM offers the opportunity for economically sustainable exploration of metal-rich soils, but its full commercial viability remains constrained under current conditions as scientists are actively searching for the identification and utilization of new hyperaccumulator plant species in different locations worldwide, while creating new relationships and business avenues within the mining industry. Overall, this review highlights the current status of PM technology and the plants used, emphasizing the need for further research to enhance its commercial implementation and its potential to assist the mining industry. We conclude that PM, although a relatively new and unexplored concept, may provide economic and environmental benefits to soil end-users and managers who must cultivate on metal-contaminated soils as PM may turn yield shortages (of specific commercial crops) to benefits if high-yield hyperaccumulators are cultivated for industrial valorization of their high metal-content biomass.

“…Gradinaru et al (2014) determined the content of phenolic compounds in methanol extract from H. arenarium inflorescences with a phenols total content of 160.2 mg/g. Helichrysum arenarium contains many trace elements, including silver and gold (Vural & Safari, 2022), but the content of trace elements in raw materials depends on the geological environment of the plant (Vural, 2018).…”

Obesity increases the risk of developing various pathological conditions such as metabolic syndrome, type 2 diabetes, non-alcoholic fatty liver disease, and cardiovascular disease. For mild correction and even treatment of obesity, drugs based on medicinal plants are increasingly being used. This work aims to determine the overall effect of Helichrysum arenarium inflorescences on physiological activity and metabolic processes in model animals fed a diet rich in fat and carbohydrates. In a 27-day experiment on 18 laboratory rats fed a diet with high-fat content and 20% fructose solution, we determined the effect of 0.4% and 4.0% dry inflorescences of H. arenarium from the feed mass on the animals' physiological activity and metabolic processes. The body weight of rats in the control group reached 121.7% of the initial body weight; when consuming 0.4% and 4.0% H. arenarium in the diet, this indicator was lower – 109.6% and 111.2%, respectively. Dry inflorescences of H. arenarium in the rats’ diet at a dose of 0.4% caused a decrease in the relative mass of the heart and thymus and an increase in the relative mass of the caecum and colon. A diet with the addition of H. arenarium caused a change in blood biochemical parameters: an increase in the urea concentration and urea nitrogen, and a decrease in the glucose concentration and protein coefficient. Helichrysum arenarium at both concentrations significantly increased the gamma-glutamyltransferase and alkaline phosphatase activity with a decrease in alpha-amylase activity in the blood. A 0.4% dose of inflorescences of the food mass caused a decrease in AST activity, and 200 g sharply increased blood ALT activity. The consumption of dried H. arenarium inflorescences decreased hematocrit, haemoglobin concentration, erythrocyte and platelet counts, and increased the percentage of eosinophils and monocytes. A decrease in physical activity and an intensification of emotional state were found in the animals after eating dry inflorescences of H. arenarium, regardless of the dose compared with the control group of animals. Significant changes in the orientation activity of the animals were not observed. The obtained results show that adding dry H. arenarium inflorescences as a food supplement to a high-calorie diet is safe, does not cause pathological changes and side effects, and significantly affects metabolic processes. This provides theoretical support for the use of dried H. arenarium inflorescences for the production of nutraceutical and pharmacological products for the correction of metabolic disorders in humans and animals. The doses and duration of their use require further research.
