lei gong teng, (thunder god vine)
Translated and edited by:
The herb of lei gong teng comes from the roots,
leaves and flowers of the tripterygium wilfordii
Hook. f. It is collected during summer and autumn.
Lei gong teng is a deciduous climbing vine growing
to 12 meters, with brown, angular, downy twigs.
The leaves are light green, smooth on top, and pale
gray with light hairs underneath. They have crenate
margins and pointed apexes, and are ovate to elliptic,
5-15 cm long, 2.5 - 7 cm wide. The scented
hermaphroditic (having male and female organs) flowers,
which bloom in September, are small and whitish with
five petals and are about 9 mm across, in terminal panicles
in July. The fruit is 3-winged, and brownish red, about
1.5 cm long. The plant can grow in light (sandy), medium
(loamy) and heavy (clay) soils. It can survive in acid,
neutral and basic (alkaline) soil. It can grow in semi
-shade (light woodland) or no shade. It requires moist soil.

1. Effects on immune system
2. Anti-inflammatory effects
Triptolide and tripdiolide ,
() are highly effective in treating cancer.
Using alcohol extract of lei gong teng, triptolide or
tripdiolide on mice with leukemia L1210, (50~400mcg/kg),
showed that the therapy was highly effective .
The effective dosage for mice with L1210 and P388 was
0.1mg/kg. Using triptolide of 0.25mg and 0.2mg/kg on
mice with leukemia L615, has proved to prolong the
survival rates to more than 159.8% and 87.8% respectively and also has caused some of the mice to survive long term.
Using spleen cell L615, once a month continually for three
months to attack the cancer cells that survived long term,
did not affect the survival rate of the mice or cause them
to get ill [24,58,59].

7. Effects on Arthritis
The active ingredient of lei gong teng, triptolide, can inhibit the abnormal growth of immune cells that cause arthritis.
Rheumatoid arthritis is an autoimmune disease where the immune system attacks the parts of the body. In rheumatoid arthritis the immune system attacks the linings of the joints. Other parts of the body like blood vessels, heart, kidneys, lungs and brain and also be affected. The most affected joints are the hands, feet, wrists, elbows and knees but almost all joints can be affected.
10. Other Effects
Effect of triptolide on cardiac allograft survival in mice
triptolide cardiac allograft allograft rejection
Abstract This paper was designed to evaluate the effect of
triptolide (Tri) on cardiac allograft survival in mouse ear.
In our studies triptolide was demonstrated to suppress the
rejection of cardiac allograft in mouse ear. The effect was
both doseª² dependent and timeª² dependent. In addition,
the studies also evaluted the effect of Tri on T lymphocyte
proliferation induced by Con A or mixed lymphocyte
reaction (MLR) in vitro. The results showed that Tri
notably inhibited T lymphocyte transformation (LT)
at 0.04~10 μ g/L and MLR at 0.2~10 μg/L. All these
inhibitory effects were timeª² dependent. Maximal
inhibition of LT and MLR was observed when Tri was
added in the first 12 h of incubation. The effect of Tri
on Con Aª² induced IL- 2 production and IL- 2R
expression of lymphocytes was assayed. It was found
that Tri at 0.4 μ g/L and 10 μ g/L had no significant
inhibitory effect on the synthesis of IL- 2 by freshly
isolated mouse splenocytes prestimulated with Con A
for 24 h and 48 h. Examination of the effect of Tri on
IL- 2 receptor expression indicated that Tri can reduce
IL- 2R expression. These results suggested that Tri could
inhibit the acute phase of transplant rejection but not to
prevent allograft rejection.
Editor Note: This may be an old document that has been
retrieved. Please contact researchers for any new
According to a report from Xin Hua She News of China,the
acute phase of transplant rejection rate dropped from
30 ~40% to 5% using triptolide.

10. Effects of toxicity
Other Research: Four compounds purified from
T. wilfordii may confer protection against the FSGS
(focal segmental glomerulosclerosis)
1. proliferative arthritis 類 風 濕 性 關 節 炎
(1). Dosage per day for adults: 20 to 30 g of dried stem
of lei gong teng. Use low heat to simmer for 3 to 4 hours.
Adjust the amount for children.
Take until symptoms are clear. Fifteen days after
symptoms are clear, change to every other day or every
3 days per dose; then slowly wean from it. If symptoms
do not subside after 15 days, it is deemed ineffective.
There were 60 patients. Average stay in the hospital:
3 to 4 months.
Result: 17 healed. Effective: 20. Better: 19.
Not effective: 4.
The characteristic of this herb is warm and toxic. It is
effective for acute cases. It is much less effective on
cases with deformed joints. 
(2). Combining 2/3 of lei gong teng with bark and 1/3
without bark and made into 15% tincture.
Dosage: 10 to 15 ml per day, made into 3 servings
for after meals. Continuously taken for 3 to 5 months
(average 4.5 months).
After symptoms are controlled, dosages were decreased.
healed: 18. Obviously improved: 95. Better 46.
Not effective: 6. Total effectiveness: 96.4%.
(3). Total saponins dosage 1 to 1.5 mg per day, into 3
servings, taken after meals. The largest dosage was
90 mg. During using this therapy, other medicines were
suspended. After 1 to 2 weeks, the symptoms started to
subside. After treatments, ESR and other values of proliferative arthritis indicators started to decrease.
Some of them became normal. EgC, IgA, and IgM
obviously decreased. After more than 3 months of
therapy, among 136 patients, with lessor clinical
symptoms : 24, obviously improved: 51, improved:
52, infective: 9, total effectiveness: 93.3%.

2. tonic inflammation of spinal cord
lei gong teng syrup: containing lei gong teng whole root (100 ml contains raw herb of 17 g), chen pi. Starting with 60 ml, per day, after 3 to 5 days increase to 90 ml, divide into 3 serving. Take after them meals. 20 to 30 days is one therapy period.
number of patients: 140, symptoms subsided: 28.57%, got better: 9.29%, ineffective 0.71%, obviously effective: >89.29% 
(2) lei gong teng tincture 15 to 30 ml/d, divided into 3 serving. Usually after taking it for 2 to 18 months for tonic inflammation of spinal cord, all patients show obvious improvement.

Using water decoction of lei gong teng and alcohol extract of lei gong teng:
They both contain 50 lei gong ten 50 g, and ji xue tang 50 g each. Take orally 50 ml, twice a day after meals. 30 days is on therapy period
Total patients: 193
Patients taking alcohol extract: 116
Effective rate: 86.2%
Patients taking water decoction: 77
Effective rate: 72.72%
It showed that the alcohol extract was more effective than the water decoction.

constitution of individual patients.
3). Avoid using on patients with liver problems.
Antidotes for toxicity
1). Empty stomach and induce diarrhea.
2). During the early stages, use adrenocortical hormone.
Dexamethasone 5~10mg with added 50% glucose 40 ml
can be used in IV administering, followed with
dexamethasone of 1.5mg, 3 times a day for 2~3 weeks.
Anisodamine (654-2) can also be used.
3). Use dextran 40 (low Molecular Dexran,
Rheomacrodex) 500ml IV administering, when toxin
has been absorbed but no symptom of toxicity.
20% solution of Manitol for IV administering, and
furosemide 40mg (Frusemide, Fursemide, Lasix) for
muscle injection. Pay attention to the balance of
electrolytes and correct acidosis immediately.
4). Skin allergy can be treated with antihistamines
or with traditional Chinese herbs for dispersing heat
and neutralizing toxin.
