The
extracts
failed
to
produce
any
promising
results.
Tu
and
her
team
could
not
produce
enough
qinghaosu
extract
because
research
resources
were
limited.
Tu
and
her
team
did
not
have
sufficient
safety
data
to
start
trials
on
patients.
Tu
Youyou
referred
to
the
ancient
books
of
traditional
Chinese
medicine
again,
redesigned
the
experiments
and
tried
extracting
the
qinghao
herb
at
a
low
temperature
in
order
not
to
damage
its
effective
part.
Tu
Youyou
and
her
team
managed
to
find
solutions
to
the
problem,
e.g.
using
household
water
containers
instead
of
research
equipment.
Tu
Youyou
and
her
team
volunteered
to
test
the
qinghao
extract
on
themselves.
