"What Is the Scientific Evidence for Andrographis?"


                   "Reducing Cold Symptoms 

                   "Three double-blind placebo-controlled studies
enrolling a total of about 250 participants have found that andrographis
significantly reduces the duration and severity of cold
symptoms.11,12,13 For example, a 4-day double-blind placebo-controlled
trial of 158 adults with colds found that treatment with andrographis
significantly reduced cold symptoms.14
                   Participants were given either placebo or 1,200 mg
daily of an andrographis extract standardized to contain 5%
andrographolide. The results showed that by day 2 of treatment, and even
more by day 4, individuals who were given the actual treatment
experienced significant improvements in symptoms as compared to
participants in the placebo group. The greatest response was seen in
earache, sleeplessness, nasal drainage, and sore throat, but other cold
symptoms improved as well. 

                   Similar benefits were seen in two double-blind
placebo-controlled studies of an herbal combination treatment containing
both andrographis and Eleutherococcus, enrolling a total of over 200
individuals.15 

                   Another double-blind study, which involved 152
adults, compared the effectiveness of andrographis (in doses of 3 g per
day or 6 g per day, for 7 days) to acetaminophen for the treatment of
sore throat and
                   fever.16 The higher dose of andrographis (6 g)
decreased symptoms of fever and throat pain, as did acetaminophen, while
the lower dose of andrographis (3 g) did not. 

                   There were no significant side effects in either
group. 

                   Preventing Colds

                   According to one double-blind placebo-controlled
study, andrographis may increase resistance to colds.17 A total of 107
students, all 18 years old, participated in this 3-month-long trial that
used a dried extract of andrographis. Fifty-four of the participants
took two 100-mg tablets standardized to 5.6% andrographolide
daily—considerably less than the 1,200 to 6,000 mg per day that has been
used in studies on treatment of colds. The other 53 students were given
placebo tablets with a coating identical to the treatment. Then, once a
week throughout the study, a clinician evaluated all the participants
for cold symptoms. 

                   By the end of the trial, only 16 people in the group
using andrographis had experienced colds, compared to 33 of the
placebo-group participants. This difference was statistically
significant, indicating that andrographis reduces the risk of catching a
cold by a factor of two as compared to placebo.
