¿Cómo Podría Beneficiar la Melatonina a la Depresión, los Trastornos Autoinmunes y el Cáncer?

Por el Dr. Mercola

La hormona melatonina desempeña muchos roles importantes en su salud, desde ayudarle a dormir mejor hasta reforzar su sistema inmunológico, lo cual ralentiza el envejecimiento cerebral, reduce los ataques de migraña, protege la masa ósea y previene el cáncer.

Una deficiencia de exposición a la luz solar durante el día, combinado con la iluminación artificial hasta altas horas de la noche interrumpe su reloj biológico y, por tanto, la producción de melatonina, y esta interrupción puede provocar una serie de efectos adversos para la salud.

De hecho, la melatonina ha sido objeto de investigación preclínica en más de 100 diferentes aplicaciones de enfermedades, muchas de las cuales están relacionadas con su necesidad de dormir. Leer Más

Forget Viagra – acupuncture could stave off erectile dysfunction, experts claim

  • A study concluded alternative medication can be beneficial for men with ED
  • Acupuncture gave men about half a minute longer than they had previously
  • Experts claim it is important to investigate alternatives since some men may not get Viagra – either out of embarrassment or due to a long doctor waiting list 

Acupuncture could help men with premature ejaculation, a new report claims.

The improvements were small, and the studies were of varying quality.

However, researchers in the UK concluded various alternative treatments – including acupuncture, Chinese herbal medicine, Ayurvedic herbal medicine and a Korean topical cream – have significant desirable effects.

Experts claim the finding could bring welcome relief for men who have not got Viagra out of embarrassment, or are marred by a months-long wait to see a doctor.

‘It’s important to evaluate the evidence for other therapies,’ said lead author Katy Cooper of the University of Sheffield.

‘To our knowledge, this is the first systematic review to assess complementary and alternative medicine for premature ejaculation.

‘There are a range of treatments available for premature ejaculation, including drug treatments, behavioral techniques and counseling.

‘However, some men may not want to visit the doctor, take drugs long-term or be on a long wait list for counseling.

In the current study, published in the journal Sexual Medicine, researchers evaluated 10 randomized controlled trials that included comparisons either to another type of treatment or to a placebo.

Two studies were of acupuncture, five were of Chinese herbal medicine, one of Ayurvedic herbal medicine and two of Korean topical ‘severance secret’ cream.

Together, the two acupuncture studies found that the treatment slightly increased intravaginal ejaculatory latency time (IELT) by about half a minute compared to placebo.

Chinese herbal medicine increased IELT by about two minutes, Ayurvedic herbal medicine increased IELT by nearly a minute and topical cream increased IELT by more than eight minutes.


Premature ejaculation is defined by reaching orgasm too quickly during sex, but there is no strict definition of ‘too quickly’.

A long-term problem can be linked to bad early sexual experiences or abnormal nerve signals.

However, if the condition develops later in life, then health problems such as type 2 diabetes, high blood pressure or excessive drinking could be to blame.

Stress and depression can also play their part.

If you are concerned, talk to your doctor, who may prescribe dapoxetine (a mild anti-depressant, brand name Priligy) which can help if taken a few hours before sex.

In some instances, a combination of traditional and alternative options was the most effective.

For example, Chinese medicine paired with selective serotonin reuptake inhibitors (SSRIs) increased IELT by two minutes longer than SSRIs alone and nearly three minutes longer than the Chinese medicine alone.

‘There are no approved treatments for premature ejaculation,’ said Donald Patrick, vice chair for research at the University of Washington in Seattle.

‘This is a common condition that has serious psychological effects on relationships,’ said Patrick, who wasn’t involved in the study.

‘We need treatments to address it, and it should be treated with equal seriousness as erectile dysfunction.’

The prevalence of premature ejaculation is difficult to measure because of the differing definitions of the problem and some men’s reluctance to report it.

Some studies suggest that between 20 and 30 percent of men report early ejaculation concerns, but the International Society for Sexual Medicine estimates that about 4 percent of men have a lifelong condition.

‘Although it is not openly discussed in the media – at least not as much as erectile problems have been discussed in the post-Viagra era – numerous studies report men feel frustrated, depressed and anxious because of this problem,’ said Ege Can Serefoglu of the Bagcilar Training and Research Hospital in Istanbul, Turkey.

The main limitation of the study is the underlying weakness of the studies evaluated.

Bias was unclear in most of the studies, and only five used stopwatches to measure IELT, which is the ‘gold standard’ for premature ejaculation studies, Patrick said.

In addition, the authors write, the studies are so different, it’s tough to draw conclusions about the different options.

For example, the five Chinese medicine studies tested different substances, including Qilin pills, Yimusake and Uighur.

Some studies, but not all, discussed side effects such as gastrointestinal discomfort, dizziness, mild pain and decreased libido. When they were reported, the adverse effects were generally mild, the study team writes.

‘Nowadays, I am encountering alternative medicine-obsessed patients more than I used to, and it doesn’t make sense to argue with them about the treatment they want,’ Serefoglu said.

‘After all, the placebo is a well-known clinical phenomenon, and some of my patients report surprisingly favorable outcomes.’
