Significant Accounting Policies [Text Block]	NOTE 3. Basis of Accounting and Principles of Consolidation The accompanying consolidated financial statements are unaudited. These unaudited interim consolidated financial statements have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not December 31, 2021 not 10 December 31, 2021. September 30, 2022 three nine September 30, 2022 2021. The accompanying unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, PLx Opco Inc. All significant intercompany balances and transactions have been eliminated within the unaudited consolidated financial statements. Use of Estimates The preparation of our unaudited consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenues and expenses during the reporting period. In the accompanying unaudited consolidated financial statements, estimates are used for, but not Inventory Inventory is stated at the lower of cost or net realizable value, using the first first September 30, 2022 December 31, 2021 Description September 30, 2022 December 31, 2021 (in thousands) Raw Materials $ 361 $ 132 Work-in-Progress - 338 Finished Goods 2,817 1,988 Total Inventory $ 3,178 $ 2,458 The Company regularly reviews inventory quantities on hand and assesses the need for an allowance for obsolescence based on estimates of net realizable value. During the three nine September 30, 2022, Revenue Recognition The Company analyzes contracts to determine the appropriate revenue recognition using the following steps: (i) identification of contracts with customers; (ii) identification of distinct performance obligations in the contract; (iii) determination of contract transaction price; (iv) allocation of contract transaction price to the performance obligations; and (v) determination of revenue recognition based on timing of satisfaction of the performance obligation. The Company recognizes revenue upon the satisfaction of its performance obligations (upon transfer of control of promised goods or services to customers) in an amount that reflects the consideration to which it expects to be entitled to in exchange for those goods or services. Deferred revenue results from cash receipts from or amounts billed to customers in advance of the transfer of control of the promised services to the customer and is recognized as performance obligations are satisfied. When sales commissions or other costs to obtain contracts with customers are considered incremental and recoverable, those costs are deferred and then amortized as selling and marketing expenses on a straight-line basis over an estimated period of benefit. The Company began generating revenue in the U.S. from its sales of VAZALORE in 81 325 third 2021 81 325 three September 30, 2022. 81 325 nine September 30, 2022. three nine September 30, 2021, 81 Nature of Goods and Services The Company generates revenue from the sale of its VAZALORE products through a broad distribution platform that includes drugstores, mass merchandisers, grocery stores, and e-commerce channels, all of which sell its products to consumers. Finished goods products are typically shipped FOB destination and accordingly, the Company recognizes revenue upon delivery to the customer or pick-up by the customer’s carrier. Satisfaction of Performance Obligations The Company had no September 30, 2022. Variable Consideration Provisions for certain customer promotional programs, product returns and discounts to customers are accounted for as variable consideration and recorded as a reduction in sales, based on an estimate of future returns, and customer prompt payment discounts, redemption of coupons by consumers and trade promotional allowances paid to customers. These allowances cover extensive promotional activities, primarily comprised of cooperative advertising, slotting, coupons, periodic price reduction arrangements, and other in-store displays. The reserves for sales returns and consumer and trade promotion obligations are established based on the Company’s best estimate of the amounts necessary to settle future and existing obligations for products sold as of the balance sheet date. The Company uses trend experience and coupon redemption inputs to determine coupon reserve requirements and uses forecasted customer and sales organization inputs, and historical trend analysis for consumer brands to determine the reserves for other promotional activities and sales returns. The balance of reserves for sales returns and consumer and trade promotion obligations, reflected in the accompanying unaudited consolidated balance sheets in accounts payable and accrued liabilities, was $1.0 million and $1.3 million as of September 30, 2022 December 31, 2021, Advertising Advertising costs are expensed as they are incurred. The Company incurred advertising costs of $1.4 million and $16.6 million during the three nine September 30, 2022, three nine September 30, 2021 Income (Loss) Per Share In periods of net loss, basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period. The Company’s Series A convertible preferred stock (the “Series A Preferred Stock”) and Series B convertible preferred stock (the “Series B Preferred Stock” and, together with the Series A Preferred Stock, collectively the “Preferred Stock”) contain non-forfeitable rights to dividends, and therefore are considered to be participating securities; in periods of net income, the calculation of basic earnings per share excludes from the numerator net income attributable to the Preferred Stock and excludes the impact of those shares from the denominator. In periods of net loss, diluted loss per share is calculated similarly to basic loss per share because the impact of all potential dilutive common shares is anti-dilutive. For periods of net income, diluted earnings per share is computed using the more dilutive of the “two class method” or the “treasury method.” Dilutive earnings per share under the “two class method” is calculated by dividing net income available to common stockholders as adjusted for the participating impacts of the Preferred Stock, by the weighted-average number of shares outstanding plus the dilutive impact of all other potential dilutive common shares, consisting primarily of common shares underlying common stock options and stock purchase warrants using the treasury stock method. Dilutive earnings per share under the “treasury method” is calculated by dividing net income available to common stockholders by the weighted-average number of shares outstanding plus the dilutive impact of all potential dilutive common shares, consisting primarily of common shares underlying common stock options and stock purchase warrants using the treasury stock method, and convertible preferred stock using the if-converted method.

Fair Value Disclosures [Text Block]	NOTE 6. Fair value is defined as the price that would be received in the sale of an asset or that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company has categorized all investments recorded at fair value based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows: ● Level 1: ● Level 2: 1, ● Level 3: The Company’s financial instruments (cash and cash equivalents, receivables, and accounts payable) are carried in the consolidated balance sheet at cost, which reasonably approximates fair value based on their short-term nature. The Company’s warrant liability is recorded at fair value, with changes in fair value being reflected in the statements of operations for the period of change. Financial assets and liabilities measured at fair value on a recurring basis The Company evaluates financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them each reporting period. This determination requires the Company to make subjective judgments as to the significance of inputs used in determining fair value and where such inputs lie within the hierarchy. The June 2017 3 one September 30, 2022 1 2 3 4 The Series A Preferred Stock and the Series B Preferred Stock both contain a contingent put option and, accordingly, the Company considered the put options to be liabilities and accounted for them at fair value using Level 3 de minimis September 30, 2022, 3 The following table sets forth a summary of changes in the fair value of Level 3 three nine September 30, 2022: Description Balance at June 30, 2022 Established in 2022 Change in Fair Value Balance at September 30, 2022 Warrant liability $ 2,759 $ - $ (2,223 ) $ 536 Description Balance at December 31, 2021 Established in 2022 Change in Fair Value Balance at September 30, 2022 Warrant liability $ 12,818 $ - $ (12,282 ) $ 536 The following table identifies the carrying amounts of such liabilities at September 30, 2022 December 31, 2021: Description Level 1 Level 2 Level 3 Total Warrant liability $ - $ - $ 536 $ 536 Balance at September 30, 2022 $ - $ - $ 536 $ 536 Description Level 1 Level 2 Level 3 Total Warrant liability $ - $ - $ 12,818 $ 12,818 Balance at December 31, 2021 $ - $ - $ 12,818 $ 12,818 Financial assets and liabilities carried at fair value on a non-recurring basis The Company does not Non-financial assets and liabilities carried at fair value on a recurring basis The Company does not Non-financial assets and liabilities carried at fair value on a non-recurring basis The Company measures its long-lived assets, including property and equipment and goodwill, at fair value on a non-recurring basis when they are deemed to be impaired.

Basis of Accounting, Policy [Policy Text Block]	Basis of Accounting and Principles of Consolidation The accompanying consolidated financial statements are unaudited.

All significant intercompany balances and transactions have been eliminated within the unaudited consolidated financial statements.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of our unaudited consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenues and expenses during the reporting period. In the accompanying unaudited consolidated financial statements, estimates are used for, but not

Revenue from Contract with Customer [Policy Text Block]	Revenue Recognition The Company analyzes contracts to determine the appropriate revenue recognition using the following steps: (i) identification of contracts with customers; (ii) identification of distinct performance obligations in the contract; (iii) determination of contract transaction price; (iv) allocation of contract transaction price to the performance obligations; and (v) determination of revenue recognition based on timing of satisfaction of the performance obligation. The Company recognizes revenue upon the satisfaction of its performance obligations (upon transfer of control of promised goods or services to customers) in an amount that reflects the consideration to which it expects to be entitled to in exchange for those goods or services. Deferred revenue results from cash receipts from or amounts billed to customers in advance of the transfer of control of the promised services to the customer and is recognized as performance obligations are satisfied. When sales commissions or other costs to obtain contracts with customers are considered incremental and recoverable, those costs are deferred and then amortized as selling and marketing expenses on a straight-line basis over an estimated period of benefit. The Company began generating revenue in the U.S. from its sales of VAZALORE in 81 325 third 2021 81 325 three September 30, 2022. 81 325 nine September 30, 2022. three nine September 30, 2021, 81 Nature of Goods and Services The Company generates revenue from the sale of its VAZALORE products through a broad distribution platform that includes drugstores, mass merchandisers, grocery stores, and e-commerce channels, all of which sell its products to consumers. Finished goods products are typically shipped FOB destination and accordingly, the Company recognizes revenue upon delivery to the customer or pick-up by the customer’s carrier. Satisfaction of Performance Obligations The Company had no September 30, 2022. Variable Consideration Provisions for certain customer promotional programs, product returns and discounts to customers are accounted for as variable consideration and recorded as a reduction in sales, based on an estimate of future returns, and customer prompt payment discounts, redemption of coupons by consumers and trade promotional allowances paid to customers. These allowances cover extensive promotional activities, primarily comprised of cooperative advertising, slotting, coupons, periodic price reduction arrangements, and other in-store displays. The reserves for sales returns and consumer and trade promotion obligations are established based on the Company’s best estimate of the amounts necessary to settle future and existing obligations for products sold as of the balance sheet date. The Company uses trend experience and coupon redemption inputs to determine coupon reserve requirements and uses forecasted customer and sales organization inputs, and historical trend analysis for consumer brands to determine the reserves for other promotional activities and sales returns. The balance of reserves for sales returns and consumer and trade promotion obligations, reflected in the accompanying unaudited consolidated balance sheets in accounts payable and accrued liabilities, was $1.0 million and $1.3 million as of September 30, 2022 December 31, 2021,

Earnings Per Share, Policy [Policy Text Block]	Income (Loss) Per Share In periods of net loss, basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period. The Company’s Series A convertible preferred stock (the “Series A Preferred Stock”) and Series B convertible preferred stock (the “Series B Preferred Stock” and, together with the Series A Preferred Stock, collectively the “Preferred Stock”) contain non-forfeitable rights to dividends, and therefore are considered to be participating securities; in periods of net income, the calculation of basic earnings per share excludes from the numerator net income attributable to the Preferred Stock and excludes the impact of those shares from the denominator. In periods of net loss, diluted loss per share is calculated similarly to basic loss per share because the impact of all potential dilutive common shares is anti-dilutive. For periods of net income, diluted earnings per share is computed using the more dilutive of the “two class method” or the “treasury method.” Dilutive earnings per share under the “two class method” is calculated by dividing net income available to common stockholders as adjusted for the participating impacts of the Preferred Stock, by the weighted-average number of shares outstanding plus the dilutive impact of all other potential dilutive common shares, consisting primarily of common shares underlying common stock options and stock purchase warrants using the treasury stock method. Dilutive earnings per share under the “treasury method” is calculated by dividing net income available to common stockholders by the weighted-average number of shares outstanding plus the dilutive impact of all potential dilutive common shares, consisting primarily of common shares underlying common stock options and stock purchase warrants using the treasury stock method, and convertible preferred stock using the if-converted method.
