RichSource

"RichSource" appears to refer to more than one health-related company, and the best current exact match is not a drug-development biotech. The clearest active operating entity using the name today is Shandong Richsource Biological Technology Co., Ltd., a China-based oral care manufacturer that provides OEM/ODM and private-label production of dental floss picks, interdental brushes, tongue scrapers, toothpicks, and related oral hygiene products. It markets itself as a high-tech enterprise focused on large-scale manufacturing, customization, and export rather than therapeutic drug R&D. A separate U.S. entity, RichSource Stem Cells, Inc., marketed perinatal tissue-derived products such as RICHGEN and received an FDA untitled letter in November 2019 concerning unapproved stem cell-related marketing claims. Because the requested name is ambiguous, this record prioritizes the currently active Shandong Richsource entity while noting the distinct U.S. stem-cell company in other fields.
