CELERY EXTRACT

 

Introduction

 

Celery is a member of the Umbelliferous family along with carrots,

parsley, and fennel. The modern celery originated from wild celery

native to the Mediterranean where its seeds were once highly valued

as a medicine.

 

Like many other folk medicines, modern research is upholding the

medicinal value of this common plant.

 

In particular, scientists are evaluating the most powerful of the

healing factors of celery, a compound known as 3-n-butylphthalide or

3nB for short.

 

What is 3nB?

 

3nB is a compound that is unique to celery and is responsible for

the characteristic flavor and odor of celery.

 

3nB was discovered as the active component of celery in response to

investigations by researchers seeking to explain some of the

medicinal effects of celery including the lowering of blood pressure

and the relief of arthritis.

 

3nB first drew significant scientific attention when researchers at

the University of Chicago Medical Center identified it as the factor

in celery responsible for the blood pressure lowering effect of

celery.

The research was prompted by one of the researcher's father, who

after eating a quarter-pound of celery every day for one week

observed his blood pressure dropped from 158 over 96 to a normal

reading of 118 over 82.

 

Subsequent animal studies found that a very small amount of 3nB

lowered blood pressure by 12 to 14% and also lowered cholesterol by

about 7%.

 

How does 3nB lower blood pressure?

 

The blood pressure lowering effect of 3nB appears to be a result of

several effects.

 

First of all, let me explain exactly what blood pressure refers to.

It refers to the force with which your blood flows

through the vessels. High blood pressure is usually the result of

too much fluid there is in your blood and how flexible or resistant

your blood vessels are.

 

Retention of sodium (salt) leads to increased fluid volume in the

blood while hardening of the arteries and the hormones

released during stress lead to loss of flexibility or constriction

of blood flow.

 

If you put your thumb over a garden hose, the pressure

against your thumb and the resultant pressure of the flow of water

out of the hose can be reduced by either turning down the faucet

(reducing the fluid volume) or by letting more water flow out the

end of the hose (dilating the vessel).

 

In treating high blood pressure, doctors usually prescribe diuretics

(water pills) to reduce the fluid volume and

vasodilators to relax the arteries to reduce the resistance of blood

flow or beta-blockers to turn down the pumping action of the heart.

 

3nB appears to help lower blood pressure by both acting as a

diuretic and vasodilator through impacting the production of

prostaglandins (discussed below) as well as acting in a similar

manner to drugs known as calcium-channel blockers.

3nB has also been shown to lower blood cholesterol levels and

reduce the formation of arterial plaque in experimental studies

(animal and test tube studies).

 

This effect may increase the elasticity of the blood vessels and

also lead to lower blood pressure readings.

 

3nB also appears to promote some effects on areas and systems of

the brain that control vascular resistance.

 

The benefit of celery extract in high blood pressure is its apparent

safety and the fact that it has a very unusual mechanism of action

as a diuretic.

 

Most diuretics change the ratio of sodium to potassium in the

blood and as a result dangerous side effects can occur as a result

of either too much potassium or sodium.

 

In contrast, celery extract acts as a diuretic but does not alter

the ratio of sodium to potassium in the blood.

 

The research on the blood pressure lowering effect of celery and

celery extracts is quite preliminary, but I think it is certainly

worth the effort to give it a try as some people have noted

significant reductions.

 

What research will probably show is that some people with

high blood pressure will respond to celery extract while others will

not. This occurrence is not unusual as physicians treating high

blood pressure will tell you that there is a similar phenomena with

conventional drugs used in high blood pressure.

 

Another real advantage of celery extract over conventional drugs

used in high blood pressure is that the drugs lower blood flow to

the brain.

 

While this effect is helpful in reducing the likelihood of stroke,

it often leaves people taking these drugs feeling tired, depressed,

dizzy, and forgetful.

 

Celery extract on the other hand has actually been shown

to not only help prevent stroke in animal studies, but also improve

blood flow as well and act to protect the brain and enhance energy

production with the brain in a similar manner to Ginkgo biloba

extract.

 

It has produced dramatic recovery in neurological and brain

function in animals in studies that simulate a stroke.

 

It has also been shown to significantly increase lifespan in animal

studies.

 

How much celery or celery extract should I take for high blood

pressure?

 

My recommendation is to either consume 8 ribs of celery per day or

take a celery extract standardized to contain 85% 3nB and other

celery phthalides at a dosage of 75 to 150 mg twice daily.

 

What other effects have been noted with 3nB?

 

3nB has shown tremendous promise as an anti-cancer phytonutrient and

detoxification aid in an experimental animal model,12 but it is its

use as a pain reliever in arthritis, fibromyalgia, and gout that is

getting most of the attention.

 

A celery extract standardized to contain 85% 3nB and other celery

phthalides has been evaluated in the treatment of " rheumatism " – the

general term used for arthritic and muscular aches and pain.

 

In these studies efficacy was evaluated by well-established

clinical

protocols used to measure the effectiveness of conventional drugs

used in arthritis and muscular pain. This protocol allows objective

measures of clinical pain that can be assessed statistically and for

individual comparisons.

 

Due to the chronic, fluctuating nature of rheumatism, the design of

the study was a longitudinal study. This sort of study

compares the results achieved when using the active substance to a

time when it is not used.

 

During the active phase of the 12-week study, the 15 subjects

suffering from either osteoarthritis, osteoporosis or gout received

34 mg of a proprietary celery extract standardized to contain 85%

phthalides twice daily.

 

The pain had been present for approximately 10 years in a

remittent or continual form and it led to a lack of joint mobility

and pain that prevented the carrying out of household duties,

hobbies and activities involved in employment of these subjects. The

results of the study were extremely positive and quite statistically

significant.

 

The chance that such a positive effect in reducing pain in these

subjects was a placebo effect was less than 1 in 1000. Subjects

experienced significant pain relief after 3 weeks of use with the

average reduction in pain scores of 68% and some subjects

experiencing complete 100% relief from pain.

 

Most subjects achieved maximum benefit after six weeks of use

although some did notice improvements the longer the extract was

used. Detailed blood chemistry as well as clinical evaluation in

these test subjects did not turn up any side effects.

 

Many subjects noticed a diuretic effect, but no changes were noted

in the sodium and potassium balance (the significance of this effect

was discussed above).

 

Based on the positive results in this small pilot study, a larger 70

patient study was conducted. Test subjects received 75 mg of the

celery extract twice daily for three weeks.

 

At this higher dosage, subjects reported even better results than

in the pilot study.

 

Statistically and clinically significant reductions were noted in

pain scores, mobility, and quality of life.

 

Again no side effects were noted other than the diuretic effect

with no changes in the sodium and potassium balance.

 

It appears to be particularly helpful for sufferers of gout as 3nB

appears to lower the production of uric acid by inhibiting the

enzyme xanthine oxidase.

 

What is the proper dosage and are their any side effects?

 

Over 100,000 people in Australia have now used this proprietary

celery seed extract standardized at 85% phthalides without any

reports of side effects.

 

The current recommendations for joint and muscle complaints

based on the information now available from trials as well as

clinical experience are the following (based upon using a celery

seed extract standardized to contain 85% 3nB and other phthalides):

 

For the relief of join and muscle pain (including pain due to

osteoarthritis, rheumatoid arthritis, and fibromyalgia): one tablet

two to three times daily.

 

 

For gout: two tablets twice daily. NOTE: The initial blood uric acid

measurements may increase in people with gout as uric acid crystals

begin to dissolve.

 

Do you have to take the celery extract continuously to maintain

benefits in relieving joint and muscle pain?

 

Yes. Results from the studies conducted to date indicate that as

long as the celery extract is used it keeps pain at bay. But, if it

is stopped the pain tends to recur.

 

How does 3nB work to produce all of these benefits?

 

Based upon al of the existing research it is clear that 3nB exerts a

profound effect on many of the body's control systems. Chief among

them the prostaglandin system.

 

Prostaglandins are chemicals that mediate or control many important

body processes including regulating inflammation, pain, and

swelling; blood pressure; and heart, digestive, and kidney

function as well. Some of the effects noted for 3nB on the

prostaglandin system are quite unique and novel.

 

Rather than simply inhibiting the production of prostaglandins by

blocking enzymes that produce them like aspirin or even the more

expensive and selective Cox-2 inhibitors, 3nB appears to help

restore balance in the prostaglandin system.16 Exactly how it

accomplishes this effect is still a mystery.

 

Drug companies are researching the unique effects of 3nB in order

to develop drugs that can be patented and sold for a huge profit. It

does not look like that line of research is necessary, however.

 

 

Can I take celery extract with conventional anti-inflammatory drugs?

 

Yes. There does not seem to be any adverse interactions with

conventional drugs.

 

Are there any contraindications?

 

Since the effects of celery extract have not been evaluated for

safety

in pregnancy, it is generally recommended that it not be used during

pregnancy or lactation. No other contraindications are presently

known.

I would advise individuals taking the drug Coumadin (warfarin) to be

closely monitored by their physician when starting to use celery

extract. It is just a precautionary recommendation.
