RULE
      13a-14(a) CERTIFICATION


AS
      ADOPTED PURSUANT TO SECTION 302


OF
      THE
      SARBANES-OXLEY ACT OF 2002





I,
      Judy
      M. Robinett, certify that:





1.
      I have
      reviewed this quarterly report on Form 10-QSB of Medical Discoveries, Inc.,
      a
      Utah corporation (the “registrant”);





2.
      Based
      on my knowledge, this quarterly report does not contain any untrue statement
      of
      a material fact or omit to state a material fact necessary to make the
      statements made, in light of the circumstances under which such statements
      were
      made, not misleading with respect to the period covered by this quarterly
      report;





3.
      Based
      on my knowledge, the financial statements, and other information included in
      this quarterly report, fairly present in all material respects the financial
      condition, results of operations and cash flows of the registrant as of, and
      for, the periods presented in this quarterly report;





4.
      I am
      responsible for establishing and maintaining disclosure controls and procedures
      (as defined in Exchange Act Rules 13a-15(e) and 15d -15(e)) for the registrant
      and we have:





a)
      Designed such disclosure controls and procedures to ensure that material
      information relating to the registrant is made known to me by others within
      those entities, particularly during the period in which this quarterly report
      is
      being prepared;





b)
      Evaluated the effectiveness of the registrant’s disclosure controls and
      procedures and presented in this quarterly report my conclusions about the
      effectiveness of the disclosure controls and procedures, as of the end of the
      period covered by this quarterly report based on such evaluation;
      and





c)
      Disclosed in this report any change in the small business issuer’s internal
      control over financial reporting that occurred during the small business
      issuer’s most recent fiscal quarter (the small business issuer’s fourth fiscal
      quarter in the case of an annual report) that has materially affected, or is
      reasonably likely to materially affect, the small business issuer’s internal
      control over financial reporting; and





5.
      I have
      disclosed, based on my most recent evaluation of internal control over financial
      reporting, to the registrant’s auditors and the audit committee of registrant’s
      board of directors (or persons performing the equivalent function):





a)
      All
      significant deficiencies and material weaknesses in the design or operation
      of
      internal control over financial reporting which are reasonably likely to
      adversely affect the registrant’s ability to record, process, summarize and
      report financial information; and





b)
      Any
      fraud, whether or not material, that involves management or other employees
      who
      have a significant role in the registrant’s internal controls over financial
      reporting.











Dated:
      November 14, 2006
