Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND PRINCIPAL ACTIVITIES	NOTE 1 - The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by rules and regulations of the Securities and Exchange Commission ("SEC"). The consolidated balance sheet as of December 31, 2019 was derived from the audited consolidated financial statements of Yew Bio-Pharm Group, Inc. (individually "YBP" and collectively with its subsidiaries and operating variable interest entity, the "Company"). The accompanying unaudited interim consolidated financial statements should be read in conjunction with the summary of significant accounting policies and notes to consolidated financial statements included in the Company's annual report on Form 10-K for the year ended December 31, 2019. In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present a fair statement of the financial position as of March 31, 2020, and the results of operations and cash flows for the three-month periods ended March 31, 2020 and 2019, have been presented. The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company continually evaluates its estimates, including those related to bad debts, inventories, income taxes, and the valuation of equity transactions. The Company bases its estimates on historical experience and on various other assumptions that it believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Any future changes to these estimates and assumptions could cause a material change to our reported amounts of revenues, expenses, assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. Certain amounts from prior period financial statements have been reclassified to conform to the current period presentation. This reclassification has resulted in no changes to the Company's financial position or results of operations presented. Details of the Company's subsidiaries, variable interest entity ("VIE") and VIE's subsidiary are as follows: Name Domicile and Date of Incorporation Registered Capital Effective Ownership Principal Activities Heilongjiang Jinshangjing Bio-Technology Development Co., Limited ("JSJ") PRC US$100,000 100 % Holding company Yew Bio-Pharm Holdings Limited ("Yew Bio-Pharm (HK)") Hong Kong HK$10,000 100 % Holding company of JSJ Harbin Yew Science and Technology Development Co., Ltd.

Principles of Consolidation [Abstract]
PRINCIPLES OF CONSOLIDATION	NOTE 2 - PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the financial statements of YBP, its subsidiaries and operating VIE and its subsidiaries in which the Company is the primary beneficiary. All significant intercompany balances and transactions have been eliminated on consolidation. Pursuant to a restructuring plan intended to ensure compliance with applicable PRC laws and regulations (the "Second Restructure"), on November 5, 2010, JSJ entered into a series of contractual arrangements (the "Contractual Arrangements") with HDS and/or Zhiguo Wang, his wife Guifang Qi and Xingming Han (collectively with Mr. Wang and Madame Qi, the "HDS Shareholders"), as described below: ● Exclusive Business Cooperation Agreement ● Exclusive Option Agreement ● Equity Interest Pledge Agreement ● Power of Attorney . To the extent that the Contractual Arrangements are enforceable under PRC law, as from time to time interpreted by relevant state agencies, they constitute the valid and binding obligations of each of the parties to each such agreement. The Company believes that HDS is considered a VIE under ASC 810 "Consolidation", because the equity investors in HDS no longer have the characteristics of a controlling financial interest, and the Company, through JSJ, is the primary beneficiary of HDS and controls HDS's operations. Accordingly, HDS has been consolidated as a deemed subsidiary into YBP as a reporting company under ASC 810. YBP has no direct or indirect legal or equity ownership interest in HDS. However, through the Contractual Arrangements, the stockholders of HDS have assigned all their rights as stockholders, including voting rights and disposition rights of their equity interests in HDS to JSJ, our indirect, wholly-owned subsidiary. YBP is deemed to be the primary beneficiary of HDS and the financial statements of HDS are consolidated in the Company's consolidated financial statements. At March 31, 2020 and December 31, 2019, the carrying amount and classification of the assets and liabilities in the Company's balance sheets that relate to the Company's variable interest in the VIE and VIE's subsidiary are as follows: March 31, 2020 December 31, 2019 Assets Cash $ 367,849 $ 688,863 Accounts receivable 7,435,586 7,692,600 Accounts receivable - related parties, net of allowance for doubtful account $193,000 and 193,000 713,042 193,000 Inventories (current and long-term), net 2,940,255 2,991,237 Prepaid expenses and other assets 148,568 37,202 Long-term advance to suppliers 582,301 Long-term advance to suppliers - related parties 393,645 Prepaid expenses - related parties - 5,829 Property and equipment, net 450,894 466,025 Long-term investment in MC 3,443,236 3,009,527 Land use rights and yew forest assets, net 37,903,062 40,048,696 Operating lease assets 254,195 259,331 VAT recoverables 343,522 349,096 Total assets of VIE and its subsidiaries $ 54,976,155 $ 55,741,406 Liabilities Accrued expenses and other payables $ 163,465 $ 131,420 Accounts payable 113 7,605 Accounts payable-related parties - 16,629 Payable for acquisition of yew forests 429,200 788,741 Advance from customer 112,709 50,071 Advance from customer-related party - - Short-term borrowings 8,141,351 8,541,517 Operating lease liabilities, current 33,561 9,340 Operating lease liabilities, noncurrent 231,463 253,423 Long-term deferred income 877,166 892,375 Due to related parties and VIE holding companies 90,676 614,265 Total liabilities of VIE and its subsidiaries $ 10,079,704 $ 11,305,386 Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board ("FASB") issued new leasing guidance ("Topic 842") that replaced the existing lease guidance ("Topic 840"). Topic 842 established a right-of-use ("ROU") model that requires a lessee to record a ROU asset and lease liability on the balance sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. This guidance also expanded the requirements for lessees to record leases embedded in other arrangements and the required quantitative and qualitative disclosures surrounding leases. The Company adopted Topic 842 on its effective date of January 1, 2019 using a modified retrospective transition approach; as such, Topic 842 will not be applied to periods prior to adoption and the adoption had no impact on the Company's previously reported results. The Company elected the package of practical expedients permitted under the transition guidance within Topic 842, which allowed the Company to carry forward its identification of contracts that are or contain leases, its historical lease classification and its accounting for initial direct costs for existing leases. The impact of adopting Topic 842 was not material to the Company's result of operations or cash flows for the three months ended March 31, 2020 and 2019. The Company recognized operating lease liabilities of $350,000 upon adoption, with corresponding ROU assets on its balance sheet as of January 1, 2019. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses". The standard, including subsequently issued amendments (ASU 2018-19, ASU 2019-04, ASU 2019-05, ASU 2019-10 and ASU 2019-11), requires a financial asset measured at amortized cost basis, such as accounts receivable and certain other financial assets, to be presented at the net amount expected to be collected based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. In November 2019, the FASB issued ASU No. 2019-10 to postpone the effective date of ASU No. 2016-13 for public business entities eligible to be smaller reporting companies defined by the SEC to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is evaluating the impact of this guidance on its consolidated financial statements.

Revenue Recognition and Deferred Revenue [Abstract]
REVENUE RECOGNITION	NOTE 3 – REVENUE RECOGNITION The Company accounts for revenue arising from contracts and customers in accordance with Accounting Standards Update (ASU or Update) No. 2014-09, Revenue from Contracts with Customers ("ASC 606") Under ASC 606, the Company recognizes revenue when its customer obtains control of promised goods, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that Company will collect the consideration it is entitled to in exchange for the goods it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods promised within each contract and determines those that are performance obligations and assesses whether each promised good is distinct. The Company then recognizes as revenue the amount of the transaction price, which is allocated to the respective performance obligation, when the performance obligation is satisfied. Generally, the Company's performance obligations are satisfied when the customers take possession of the products, which normally occurs upon shipment or delivery depending on the terms of the contracts. In general, the Company's products within its segments are aligned according to the nature and economic characteristics of its products and provide meaningful disaggregation of each business segment's results of operations. Disaggregation of revenue by business segment are included in Note 12 – SEGMENT INFORMATION.

The Tax Act among other changes, reduces the U.S. federal corporate tax rate from 35% to 21%. The Company recognized provisional tax impacts related to the revaluation of deferred tax assets and liabilities and corresponding valuation allowances in its consolidated financial statements for the year ended December 31, 2018. Accordingly, the Company recognized a one-time transition tax of $1,431,835 during 2018 that represented management's estimate of the amount of U.S. corporate income tax based on the deemed repatriation to the United States of the Company's share of previously deferred earnings of certain non-U.S. subsidiaries of the Company mandated by the U.S. Tax Reform. The Company elected to pay the one-time transition tax over eight years commencing in 2018.

SUBSEQUENT EVENTS	NOTE 14 SUBSEQUENT EVENTS On May 1, 2020, the Company got a Promissory Note (the "Note") in the amount of $70,920 approved from the Paycheck Protection Program (the "PPP Loan") through Bank of America (the "Lender"). The PPP loan is a loan program of U.S. Small Business Administration (the "SBA") designated to provide a direct incentive for small business to keep their workers on the payroll due to the COVID-19 crisis. The interest rate on this Note is a fixed rate of 1.00% per annum. The Company will pay this loan in one payment of all outstanding principal plus all accrued unpaid interest on that date that is two years after the date of this Note ("Maturity Date"). In addition, the Company will pay regular monthly payments in an amount equal to one month's accrued interest commencing on that date that is seven months after the date of this Note, with all subsequent interest payments to be due on the same day of each month after that. All interest which accrues during the initial six months of the loan period will be deferred to and payable on the Maturity Date. Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid interest; then to principal. According to SBA's PPP description, the PPP loan will be fully forgiven if the funds are used for payroll costs, interest on mortgages, rent, and utilities (due to likely high subscription, at least 75% of the forgiven amount must have been used for payroll). Loan payments will also be deferred for six months. No collateral or personal guarantees are required. Neither the government nor lenders will charge small businesses any fees. Forgiveness is based on the employer maintaining or quickly rehiring employees and maintaining salary levels. Forgiveness will be reduced if full-time headcount declines, or if salaries and wages decrease. The Company received the amount of $70,920 from Bank of America on May 4, 2020.
