Chayote may help lower blood pressure: Claims

Ridlo Aryanto, Contributor, Yogyakarta

The chayote (sechium edule), a pear-shaped, light-green squash
with lengthwise furrows, is commonly used for cooking as it is
good for lodeh, a vegetable dish cooked in coconut milk, or
oseng-oseng, a stir-fried dish with chili peppers. In Central
Java the chayote is called jipang, in East Java, manisah and in
West Java, waluh siem.

It is interesting to know that chayote is not good only for
dishes but may also be effective in combating hypertension.

Many people with hypertension claim to have benefited from
chayote. The late noted man of culture Umar Kayam was one of
them. Before he died of stroke last March, he ate chayote to
lower his blood pressure. Once he jokingly told his colleague at
Gadjah Mada University, short-story writer Bakdi Sumanto, that he
should changed his name to Raden Mas Haryo Jipang because he ate
a dish containing chayote every day.

There have been many stories about how chayote can lower blood
pressure.

Bardono, 50, a resident of Pogungrejo, Yogyakarta, was
diagnosed with hypertension as far back as 2000. A batik vendor
at Beringhardjo market, Bardono once had his blood pressure soar
to as high as 240/130 mm Hg, far above the normal level.

With his hypertension at that level, he not only suffered some
pain in the nape of his neck but his heart beat faster and his
entire body felt painfully stiff.

"When he first came here, he could not walk by himself," said
Dr Setiawan Susamto, head of the hypertension clinic of Sardjito
General Hospital, Yogyakarta. This doctor has treated him in the
past year.

When he first came to the clinic, Setiawan gave him anti-
hypertension drugs such as captopril, propanolol, HCT and
diazepam. Although Bardono took the medicine regularly, when he
came back to the clinic a month later and had his blood pressure
taken, it was still quite high: 160/100 mm Hg.

Then some day in early 2002, after quite a long absence, he
returned to the same clinic and had his blood pressure taken.
Surprisingly it showed only 140/80 mm Hg.

"At first I was afraid he had a heart failure. An early
symptom of this illness is a drastic drop in the blood pressure.
After some checking, I found everything normal and he was in a
really healthy condition," said Setiawan.

What medicine has Bardono taken?

"A friend of mine in the market suggested that I drink chayote
juice twice a day for a week. I grated one whole piece of chayote
and then squeezed it to get one glass of its juice. Every day I
drank two glasses of this chayote juice. After three consecutive
days, I felt my body light and after I went to see a doctor, it
was found that my blood pressure had returned to normal," he
said.

He added that he could now eat the beef satay, a dish that he
had avoided for quite a while, and felt all right. The question
is what chemical substance does chayote contain which lowers
hypertension?

In Traditional Concoction for the Treatment of Hypertension, a
book written by Hembing Wijayakusuma and Dr Setiawan Dalimartha,
it is mentioned that a patient of hypertension must urinate a lot
to lower his/her blood pressure. He or she will need the kind of
medicine with a diuretic property.

Juice made of chayote or star fruit is good for hypertension
because both chayote and star fruit have diuretic effects.

"However, the diuretic effect of the chayote stays longer than
that of the star fruit, which lasts only some time after it is
eaten. That's why if you eat star fruit for your hypertension, it
will be under control only after you eat star fruit. As for the
chayote, its efficacy as a diuretic stays more permanently,"
writes Hembing in his book.

A more academic explanation came from Dr Suwijio Pramono, a
pharmacist of the School of Pharmacy of UGM.

"The chayote juice contains flavonoid, saponin and polifenol,
three chemicals which can effectively function as diuretics. Then
the chayote also contains alkaloid, which helps break through
obstructed blood vessels.

"Therefore, I'd rather believe that the chayote is good for
hypertension because of its alkaloid content. This substance is
good to take with the chayote being eaten raw. Unlike other
traditional medicinal herbs which need boiling, the chayote, or
its juice, can be taken without being boiled first," Suwijio
said.
