                          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 amendment to quarterly report on Form 10-QSB/A of
Medical Discoveries, Inc.;

2.    Based on my knowledge, this 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 report;

3.    Based on my knowledge, the financial statements, and other financial
information included in this 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 report;

4.    I am responsible for establishing and maintaining disclosure controls and
procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for the
registrant and I have:

      a)    designed such disclosure controls and procedures to ensure that
material information relating to the registrant, including its consolidated
subsidiaries, 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 report my conclusions about the
effectiveness of the disclosure controls and procedures as of the end of the
period covered by this report based on such evaluation; and

      c)    disclosed in this report any change in the registrant's internal
control over financial reporting that occurred during the registrant's most
recent fiscal quarter (the registrant's fourth fiscal quarter in the case of an
annual report) that has materially affected, or is reasonably likely to
materially affect, the registrant'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
functions):

      a)    all significant deficiencies in the design or operation of internal
controls 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.
