Abstract:
The objective of this study is to evaluate the efficacy of garlic extract on blood lead levels of lead exposure workers. The participants in this study were production line workers in a battery factory in Samut Prakan province. The data collection tools consist of personal questionnaires, data record forms and blood specimen collection for lead levels. The participants consisted of 90 production line workers. The method of this study was before starting the experiment, all subjects were required to fill out their personal information and to determine baseline blood lead assessments then classified into three groups (n=30 per group). Group one was a control group (the participants took a placebo), the others two groups were experimental groups (900 mg and 1200 mg garlic extract). Each group was allowed to intake garlic extract continuously for 14 days. The results were found that the reduction of blood lead levels after taking garlic extract 900 mg per day was statistically significant (p = 0.044) whereas blood lead levels for taking 1200 mg of garlic extract per day were not different. However, mean differences in blood lead levels of the garlic extract and control groups were not different
