Abstract

Alternative medicine utilizing the therapeutic effects of plants is commonly used in the community. Contaminants in the raw materials, like lead, may lead to adverse health effects. This study aimed to determine the presence or absence of lead and specifically aimed to obtain its levels in plants and commercial tea utilized as herbal medicine in Manila, Philippines. The blood levels of the heavy metals were mathematically projected as well. The concentrations were compared with the World Health Organization (WHO) and Center for Disease Control (CDC) allowable standards for plants and blood, respectively. Flame Atomic Absorption Spectrophotometry (FAAS) was used to analyze the heavy metals from the samples. All samples tested contained lead but conformed with the WHO limits at 10 ppm. However, only the tea preparation samples conformed with the CDC limit at 10 ug/dL but not the collected plants which went above the prescribed concentration. Herbs and its preparations must be decontaminated prior to use for better health provision to the Filipino people.

菲律宾马尼拉新鲜草药和商业茶叶产品中的铅含量

利用植物治疗效果的替代医学在社区中被广泛使用。原材料中的污染物，如铅，可能导致不利的健康影响。本研究旨在确定铅的存在或不存在，特别是旨在获得其在菲律宾马尼拉用作草药的植物和商业茶中的水平。血液中的重金属含量也用数学方法进行了预测。浓度分别与世界卫生组织(WHO)和美国疾病控制中心(CDC)对植物和血液的允许标准进行了比较。采用火焰原子吸收分光光度法(FAAS)分析样品中的重金属。所有检测的样本都含有铅，但符合世卫组织10ppm的限制。然而，只有茶制剂样品符合CDC的限制10 ug/dL，而收集的植物不符合规定浓度。草药及其制剂在使用前必须进行消毒，以便为菲律宾人民提供更好的保健服务。
