Related Party Transactions Disclosure [Text Block] | 10. RELATED PARTY TRANSACTIONS The Company is a party to a Royalty Agreement and License with Broady Health Sciences, L.L.C., a Texas limited liability company, (“BHS”) regarding the manufacture and sale of a product called ReStor™. George K. Broady, a former director of the Company and previously a beneficial owner of more than 5% of its outstanding common stock, is an indirect owner of BHS. Lucy Nduati, a director of the Company, has since 2013 served a number of companies controlled by George K. Broady and other Broady family members in a variety of roles focused on administration, accounting, finance, tax strategy and office management. Under this agreement (as amended), the Company agreed to pay BHS a royalty based on a price per unit in return for the right to manufacture (or have manufactured), market, import, export and sell this product worldwide by or through multi-level marketing or network marketing. The Company recognized royalties of $9,000 during each of the three-month periods ended March 31, 2026 and 2025 under this agreement. The Company is not required to purchase any product under the agreement, and the agreement may be terminated under certain circumstances with no notice. The agreement was set to terminate on March 31, 2025; however, as neither party provided the required 90-day advance notice, it has automatically renewed for an additional one-year term in accordance with its provisions.
