Remedy Description


Vaginal creams and suppositories made with neem oil are quickly becoming

the birth control method of choice in India. They are non-irritating and

easy to use while almost 100 percent effective. It's important to note,

however, that even toxic spermicides are not 100 percent effective. When

tested against human sperm neem extract (sodium nimbidinate) at 1000 mg

was able to kill all sperm in just 5 minutes and required only 30 minutes

at a 250 mg level. They have the added benefit of preventing vaginal and

sexually transmitted diseases like gonorrhea, syphilis and chlamydia.

Neem has a proven ability to prevent pregnancy. Neem oil has also been

shown to work well both before and after sex while some purified extracts

only worked before sex as a preventative. Neem oil appears to be the most

effective form of neem for birth control, particularly hexane extracted

neem oil. After a single injection of a minute amount of neem oil in the

uterine horns, a strong cell-mediated immune response reaction produced a

long term (up to 12 months) and reversible block in fertility. There were

no changes in menstrual cycles or ovarian function.

Neem oil has also been found to prevent implantation and may even have an

abortifacient effect similar to pennyroyal, juniper berries, wild ginger,

myrrh and angelica. The effects were seen as many as ten days after

fertilization in rats though it was most effective at no more than three

days. In a study on rats, neem oil was given orally eight to ten days

after implantation of the fetus on the uterine wall. In all cases, by day

15, the embryos were all completely resorbed by the body. The animals

regained fertility on the next cycle showing no physical problems.

Detailed study of the rats revealed increased levels of gamma interferon

in the uterus and enhanced local immune response in the uterus. Post

coital use of neem oil as birth control does not appear to work by

hormonal changes but produces changes in the organs that make pregnancy no

longer viable.

Years of study in India by some of the world's leading scientists resulted

in the development of a neem-based polyherbal vaginal cream that has both

spermicidal and anti-microbial action. The cream combines 25 per cent neem

seed extract with extracts from the soap nut and quinine hydrochloride.

Based on the success of these experiments, a neem-based contraceptive

cream was developed by a pharmaceutical company in India. Tests of its

effectiveness showed that it compared favorably with the chemical-based

foams and gels. It was safer and easier to use, caused no irritation or

discomfort, was nearly 100% effective, and was therefore used more

frequently than the foam or gel spermicides. The effect does not appear to

be hormonal and is considered a safe and effective alternative to other

methods that use hormones.


Neem may become the first truly effective birth control "pill" for men.

Neem oil capsules ingested for one month produced reversible male

antifertility without affecting sperm production or libido. In India and

the United States, exploratory trials show neem extracts reduced fertility

in male monkeys without inhibiting libido or sperm production.

In a test of neem's birth control effects with members of the Indian Army,

daily oral doses of several drops of neem seed oil in gelatin capsules

were given to twenty married soldiers. The effect took six weeks to become

100 percent effective, it remained effective during the entire year of the

trial and was reversed six weeks after the subjects stopped taking the

capsules. During this time the men experienced no adverse side effects and

retained their normal capabilities and desires. There were no pregnancies

of any of the wives during the period of the study.

For long term birth control for men it appears that a very minute amount

of neem oil injected in the vas deferens provides up to eight months of

birth control. The tests revealed no obstructions, no change in

testosterone production and no anti-sperm antibodies. The local lymph

nodes showed increased ability to respond to infections indicating an

immune response may be responsible for the birth control effect in men as

it is in women.
