1 cunLU-91 / 21 / 2LU-6192 patients with bronchial asthma were treated with
LU-6and LU-10. 98.9% of the patients experienced an immedi-
ate improvement; the rate of clinical remission plus marked
improvement was 76.5%. Best therapeutic results were achieved
for allergic asthma according to Western medicine (asthma due
to Cold according to TCM) and with longer needle retention
(approximately 40 minutes). The lack of blinding and control
groups reduce the value of this precise therapeutic case study.

A Chinese prospective, randomised, controlled, non-blinded trial
investigated the effect of bilateral bloodletting at LU-10, P-8,
HE-8, L.I.-2, T.B.-2and S.I.-3on heart rate and consciousness
in patients with apoplexythat had occurred within 3 days. Only
patients with mild injuries showed improved consciousness
while the heart rated increased independently of the size of
injury. Yi et al, J Tradit Chin Med 2005
LU-11LU-11Three Russian animal trials demonstrated the antipyretic
action of LU-11. LU-11 can also strengthen the effect of hypother-
mic substances, suggesting a combination with antipyretic Chi-
nese herbs. Nezhenzev et al, Biull Eksp Bio Med 1992, and

A Taiwanese prospective, randomised, non-blinded, controlled
trial (n76) investigated whether bloodletting at LU-11and
L.I.-1can prevent or treat the occurrence of laryngospasmafter
tracheal extubation in children. The incidence of laryngospasm
was significantly less in the bloodletting group (5% vs 24%). If
laryngospasm developed, this could be relieved with the treat-
ment of LU-11 or L.I.-1 within one minute in all patients. Lee

(n210) reports the significantly better effects of needling
L.I.-3and lingxiain the treatment of periarthritis of the
humeruscompared to the control group treated with local points.
Of interest is the application of lingxia, an unofficial extra point

A Turkish prospective, controlled, non-blinded, group-compari-
son trial (n55) investigated the effect of electro-acupuncture
(EA) at L.I.-4, L.I.-11, ST-25, ST-36, ST-44andLIV-3(com-
bined with auricular points shenmenand sanjiao) on obesity in
women. Treatments were given daily for 20 days. One control
group received a 1425 kcal diet for 20 days while the other con-
trol group received no treatment. There was a 4.8% weight
reduction in the EA group, whereas women on the restricted diet
had a 2.5% weight loss. Both groups showed a significant reduc-
tion in total cholesterol and triglyceride levels. In the EA group
only, LDL levels were also reduced significantly. Cabioglu et

A Chinese (Hong Kong) prospective, randomised, controlled, non-
blinded study (n29) investigated the effect of L.I.-4and P-6on
the heart rate variability (HRV) in normal subjects in fatigueand
non-fatigue statesrespectively. Only fatigued subjects showed a
significant change in HRV. The authors concluded that the effect of
acupuncture depends not only on the points selected but also on the
functional state of the subject, one of the principles of Chinese
Medicine. Li et al, Eur J Appl Physiol 2005
An unusual veterinary case study investigated the effects of
acupuncture on the immune system. According to the authors,
immunostimulant points include LI-4, LI-11, ST-36, GB-39,
SP-6, GV-14, BL-11, BL-20, BL-23, BL-24, BL-25, BL-26,
BL-27, BL-28,and Ren-12. BL-47is considered to be immuno-
suppressive. Anti-febrile points include ST-36 and Du-14.
