8. Toxicity Side Effect
The outer skin of the fruit contains
ginkgo toxin. Ginkgo phenols and ginkgo toxin possess effect of hemolysis.
Ginkgo toxin possesses an anesthetic effect on the central
nervous system of frogs. A venous injection of 0.2g/kg on rabbits
causes temporary raising of blood pressure then with subsequent
dropping of blood pressure, breathing difficulty, panic and
death. Using the neutral portion of the gingko seed for skin
injection of 6mg/kg also can cause death for mice. Using a large dosage
of ginkgo leaf extract for venous injection continually for one week
on dogs causes salivating, vomiting, diarrhea, and lack of appetite.
In lab examination of tissues, it shows the increase of mucus secretion
of the lower abdomen. Local injection causes local blood vessels to
harden. It shows that in dogs and rabbits under anesthesia, the movement
of intestines increases. A normal amount of flavonol does not affect
the blood clotting time. A large dosage can interfere with the blood
clotting time. Venous injections of 242mg/kg (in 95% of the cases,
229.6~256.2/kg could be the fatal limits), of di-flavonol
were applied to mice and caused acute toxicity symptoms of rapid
breathing, sprawling still, and eventually all died of breathing
Raw ginkgo nuts are toxic. Consuming a large amount can cause vomiting,
stomach ache, diarrhea, spasm, anxiety, and breathing difficulties.
|Present Day Applications:
|1. Labyrinthine syndrome
3. Urolithiasis (formation of calculi in the urinary tract.)
Formulae: root of gingko biloba 120 g, rock cane sugar 120 g. Boil
with water. Taken orally. 4~5 doses a week. If there is infection
of urinary track, use
hua she she cao. Drink plenty of liquid and excercise (editor
note: preferably qigong dong gong). Out of fifty patients, thirty
two were healed. Ten patients were improved. Eight patients did not
improve. Average treatment time was 133 days.
