Dark specs are herbal sediments that have settled in your tincture, which can sometimes occur during the straining process. Be sure to give your tincture a good shake before using. All of our products are carefully crafted by hand in small batches for quality assurance and tested by a California licensed lab prior to being sold at any retailer. If you are concerned with the quality of your tincture, please reach out to info@yummikarma.com and we will happily assist you!
