Modified Mai Men Dong Tang
In 2005, Hsu et al18 reported results of a clinical
investigation of a complementary TCM therapy for
asthma. This study evaluated the efficacy and safety of a
Chinese herbal formula, modified Mai Men Dong Tang
(mMMDT), for treatment of persistent, mild-to-moderate
asthma. mMMDT consists of 5 herbs (Table I). This
4-month trial included 100 patients with asthma age 5 to
18 years. The 2 active groups received 40 mg mMMDT
(40 patients) or 80 mg mMMDT (40 patients). The control
group received placebo capsules (20 patients). Western
medications as part of standard asthma therapy were provided
equally to all groups, although it is unclear whether
there were adjustments for severity of disease at baseline.
Parameters used to evaluate efficacy were changes in
FEV1, symptom score, total serum IgE, and dust mite–specific
IgE. Safety assessments included complete blood count
and liver and kidney function tests. Relative to baseline,
significantly greater increases in FEV1 were demonstrated
for both mMMDT-treated groups in comparison with
the placebo group (P < .05 for both doses of mMMDT).
Symptom scores were similarly improved in both
mMMDT treatment groups. The serum total IgE for the 80
mg/d dose ofmMMDT treatment showed a decreasing tendency,
but no statistical difference was found. No drugrelated
adverse effects were reported. Possible efficacy of
mMMDT as a monotherapy for asthma has not been tested.
Ding Chuan Tang
In 2006, Chan et al19 reported that Ding Chuan Tang
(DCT), a Chinese herbal decoction, could reduce AHR
in stabilized children with asthma in a randomized, double-
blind clinical trial. DCT contains 9 herbs (Table I).
This study enrolled children age 8 to 15 years diagnosed
as patients with mild-to-moderate persistent asthma.
They were randomly allocated to receive 6.0 g DCT or
placebo daily for 12 weeks. Self-recorded daily symptom
scores, medication scores, and morning and evening peak
expiratory flow rates were returned at monthly clinic
