The chief geophagical clay entering the West African market system comes from the village of Uzalla, Nigeria. Village inhabitants ascribe antidiarrheal properties to the clay, and they use it in traditional medicinal preparations to counteract intestinal problems. Mineralogical analyses demonstrate a striking similarity between the Uzalla village clay and the clay in the commercial pharmaceutical Kaopectate.
进入西非市场体系的主要食土性黏土来自尼日利亚的乌扎拉村。村里的居民认为这种黏土具有止泻特性，他们将其用于传统药物制剂中以对抗肠道问题。矿物学分析表明，乌扎拉村的黏土与商业药品碱式水杨酸铋中的黏土有惊人的相似之处。
