Introduction to Kidney Cleanse
Kidneys are the primary organs that remove toxins. We have two
kidneys located in the lumbar region, a little below the waist, oriented
toward the back. Each kidney weighs nearly 150 gms and is about
the size of an adult fist. They are bean-shaped and reddish brown
Anatomy of the Kidney
Each kidney has three regions - the cortex, the medulla and the renal pelvis. The outer layer,
the cortex, contains nearly 12,00,000 filtering units called nephrons, each consisting of a
glomerulus and a renal tubule. Blood flows into a network of capillaries, surrounding each
tubule, from the glomerulus, where substances that the body still needs, such as water,
glucose and certain salts, are reabsorbed and restored to the blood. In a process called filtration,
blood containing waste products, enters the glomerulus, where the
cells extract water and waste products, such as urine.
The purified blood is then returned to general circulation throughout
the body. Waste, in the form of urine, passes through the ureter into
the bladder and regulates acidity of the blood. Everyday, the body’s
entire volume of blood passes through the kidneys more than 300
times, a flow of nearly 1800 litres, almost all of which is reabsorbed
and returned to the blood stream.
The middle part, the medulla, consists of cone shaped groups of
urine collecting ducts. The inner region - the renal pelvis, branches
into cavities called major and minor calyxes. Each minor calyx gathers
urine from the medulla, which is then collected in the major calyxes
and funnelled into the ureter.
The kidneys keep the body’s chemistry balanced by removing waste
products and excess water. They also regulate blood pressure
and stimulate Red Blood Cell (RBC) production. Some of its other
- Activation of vitamin D absorption
- Elimination of metabolic wastes
- Maintaining acid-base balance (excretes alkaline salts)
- Maintaining electrolyte balance
- Maintaining fluid balance
- Prostaglandin synthesis (the female body uses this hormone for contraction of the womb during childbirth)
- Urine formation and excretion (a healthy adult passes nearly half a litre to two litres of urine a day)
The body can stay healthy with just a single kidney. However, it is
important to treat kidney disorders promptly because some disorders
progress rapidly, often affecting both kidneys, before they are even
detected. Kidney stones, kidney failures and kidney shrinkage are
some of the common problems.
Some of the major causes of kidney problems are:
- Cooked food
- Hereditary diseases
- High blood pressure
- Inflammation of kidneys (nephritis)
- Kidney damage, as a side effect of medication, particularly pain killers taken for headache, backache and joint pains
- Lower urinary tract infection, e.g., bladder infections ascending upto the kidneys
- Scarring of kidneys (caused due to reverse flow of urine
from the bladder)
The symptoms of a weak kidney can vary considerably from one
individual to another. The initial signs of the onset of kidney problems
may be general and include:
- Blood in urine
- Change in frequency and quantity of urine passed
- High/low blood pressure
- Pain in the kidney area (kidney/ureter stone)
- Pain in bones (vitamin D deficiency)
- Pain or burning sensation while passing urine, indicating an infection
- Puffy, dark grey mess below the eyes, around the face, ankles and elsewhere on the skin
- Tiredness (particularly in the evening)
Cooked food and pollution affect proper functioning of the kidneys
due to which nephrons are unable to remove toxins from the blood
properly. These toxins get accumulated, as the body is unable to
expel them naturally. Over a long period of time, these toxins form
tiny stones that are very difficult for the body to remove and require
surgery. A Kidney Cleanse dissolves these stones and dilates the
pores so that they can easily pass out of the body. A Kidney Cleanse
is also used to cleanse the kidneys from within, by removing deeply
embedded toxic wastes.
- Tea* () made from corn silk () - fresh or dried.
Ideally, the corn silk should be dried in sunlight. If it is dried properly, it
can be preserved for a long time. Washing the dried corn silk before use is strictly prohibited
as it loses a lot of its medicinal value. Moreover, the dust and impurities in it can be
removed by sedimentation process in which the corn silk is strained before use.
- Tea, made from parsley (a foreign vegetable that looks like green coriander) or coriander leaves
(), should be used fresh. Rinse them in water before boiling.
They should be strongly fragrant. If not, they may have lost most of their active ingredients, or,
- Tea made from watermelon ( ) seeds with their skin intact. The seeds can be black or
brown in colour. These can be dried and preserved. Some provision stores that sell agricultural
produce also stock watermelon seeds. They are marked ‘poison’, since they have been treated with
pesticides. Therefore, you need to wash and dry them before use. Pound them before boiling, so
that the medicine from the skin and the innards gets mixed with the water. Do not grind or wash
the seeds after crushing.
I encourage self-medication. When you are doing it for the first time,
you may adhere to the following dosage:
||Colour of Tea
||Corn silk (fresh)
||Corn silk (dried)
||Parsley / Coriander (fresh)
Observe the results by yourself and decide whether to increase or decrease the dosages for
subsequent use. You may decide the most appropriate quantity and frequency for yourself, though the
highest dosage and frequency (the maximum quantity that you can tolerate) is recommended.
Taking concentrated medicine in larger quantities yields quicker and better results as the
medicine reaches deeper into the affected organ. If nausea or any other undesirable
symptom, such as stomach pain, occur, then reduce the dosage. Some people get better results
with corn silk, while others with parsley/coriander leaves or watermelon seeds. I have found
concentrated corn silk tea to be the best for myself.
However, everyone gets some results using any of the four ingredients. Some have even reported good
results with watermelon seeds without the skins, which are available at most grocery stores.
To make concentrated tea, fill the vessel/pot with just enough water
to cover the ingredients and boil any of the three ingredients for 10
minutes. Strain the water and keep it aside. Boil the residue again with
fresh water for 10 minutes. Strain it and add it to the water set aside
in the previous step. Follow this procedure one more time or until
the mixture begins to lose colour. This indicates that the ingredient
has no more medicine left in it.
Let the strained mixture stand for a few minutes so that any
sediment present sinks to the bottom of the vessel. Carefully, without
any sudden movement, pour the upper layer of the mixture into
another vessel, until the sediment at the bottom starts flowing. Stop
and discard this sediment. This procedure, known as decantation,
can be used to separate fine residue from the mixture. Cool the
strained mixture. The medicine is now ready for use.
Drink one litre of this mixture 3-4 times or more during the day. The
mixture has to be stored in a refrigerator otherwise it will get spoiled.
It can be stored in the refrigerator for a maximum of a day or two.
If refrigerated, it may coagulate (thicken) slightly but its medicinal
properties are not affected. If you cannot drink the cold liquid, then
you may warm it to your taste. Warming does not affect its medicinal
properties (see page 183).
What results can you expect?
When toxins are accumulated in the body and the kidneys cannot
filter them out, they are circulated in the blood stream. To reduce
the ill-effects of these toxins, the body tends to keep them in a
diluted form, thereby retaining more water. When the level of water
in the blood stream increases, it causes a condition known as
oedema. This results in increased body weight, and swollen face
and ankles. During a Kidney Cleanse, the extra water retained in
the blood stream is also released. Expect an increase in urination
as a result of the cleanse.
During the course of treatment, nearly 1% of patients feel nauseous
and nearly 3% experience mild stomach pain. However, these
conditions are not severe and are caused due to the hyperactivity
of nephrons during the cleansing process. The pain subsides on its
own in 1-2 hours and does not require any treatment. The final result
is exhilarating freshness.
The first round of treatment should be over in a day and instant
improvement will be visible, including:
- Dissolution of kidney stones
- Glowing face, better skin tone with shining and fairer complexion, reduced dark circles below the eyes
- Higher energy levels
- Improved haemoglobin levels
- Improved sleep quality
- Increase in calcium levels (treatment of osteoporosis)
- Increased activity levels
- Old accumulated toxins expelled from the kidney and blood
- Regulated blood pressure (marginally high or low BP are controlled without medication)
- Relief from backache and body pain
- For females, improvement in Pre-Menstrual Symptoms (PMS) and almost all gynaecological problems
- No more bed wetting and prostrate problems
Frequently Asked Questions
Q1. Can I use all the ingredients, i.e., corn silk, parsley, coriander and watermelon seeds together?
They are to be taken only one at a time. Any one of them is good
enough for the treatment. You may try another option after a few days.
Q2. I am not able to find corn silk in sufficient quantity in the
market due to the off season. My stored corn silk has developed
a fungus. Can I still use this contaminated corn silk?
The medicinal properties of this fungus affected dried corn silk
do not change. It can be used just as well, with the same results as
fresh or dried corn silk. Keep the corn silk under the sun for a few
hours. Then follow the procedure as outlined for the preparation
process. If the corn silk has been stored without drying or under
wet conditions and has turned black, then it should not be used.
You should keep the corn silk under the sun occasionally, so
that it remains good for later use. We have mentioned the name
and addresses of a few vendors who sell ingredients for the
Cleansing Therapy on our websites www.drpiyushsaxena.com or
Q3. I cannot find watermelon seeds. Can I replace it with muskmelon
(Kejyetpee ) seeds?
Their properties are totally different. Only watermelon seeds with
their skin intact have kidney cleansing properties and not muskmelon
Q4. What diet should I follow for Kidney Cleanse?
Just stick to your regular diet and drink Kidney Cleanse tea as
much as possible. However, refrain yourself from consuming food
that is hard to digest, during the cleansing process.
Q5. What is the best time to do a Kidney Cleanse?
Kidneys function more efficiently when the stomach is empty and
the body is most relaxed in a lying down position, after midnight. I keep
a litre of corn silk tea near my bedside at night. If I happen to wake
up between 2-4 am, I drink it. This dose is in addition to my regular
dosage during the day.
Q6. I got tremendous benefit after doing a Kidney Cleanse but
after one week, I am facing the same old problems.
Sometimes, old problems manifest again, but if you monitor their
frequency and intensity, they occur at much lower levels after the
cleansing. Secondly, you are continuing to live in the same polluted
environment and eating the same food, hence, this manifestation
is very normal. Do the cleanse again and your health will improve.
You will notice instant improvement in backache, headache, general
freshness level and quality of sleep.
Q7. After following your therapy, why do I experience increased
bleeding during menstruation?
This may happen to a few women and is a good sign. You must
have felt better in your pre-menstrual symptoms and may have
experienced much less abdominal pain. As soon as the toxins
accumulated in your body are expelled, your condition will improve
and you will feel better in a day or two.
Q8. How much corn silk tea can be used for a Kidney Cleanse?
You can have as much corn silk tea as you like. Some people get
results in a single glass, while others respond better with six glasses
of the concentrated tea. Excess dosage does not harm.
Please note that in a Kidney Cleanse, the quantity of tea is not
relevant. What actually matters is the concentration of medicine in
the tea after the corn silk is boiled. That is why I recommend boiling
the corn silk three times. I ascertain that everybody will get good
results after the Kidney Cleanse. However, if you feel that the
cleanse has not given the desired results, don't suspect the efficacy
of Kidney Cleanse, rather, check the quality and quantity of
ingredients as well as the procedure followed.
Q9. How long should I boil the water for a Kidney Cleanse?
Boiling begins when the water temperature reaches 100o
that temperature, the best medicine is extracted from the corn silk.
Boiling it for 15 minutes is fine.
Q10. What should I eat during a Kidney Cleanse and an Acidity
There is no dietary restriction for doing a Kidney and an Acidity
Cleanse. You are free to eat any food or follow any diet. Kidney
cleanse tea and vegetable juices are most effective when consumed
on an empty stomach.
Q11. Should Kidney Cleanse be started on an empty stomach?
A few doses on an empty stomach will definitely improve the
quality of the cleanse. If the medicine is taken on an empty stomach,
its absorption in the blood stream will be much better.
Q12. What is an empty stomach?
Empty stomach is a state when the system has digested nearly
all the ingested food. In the morning, the stomach is empty because
every thing has been digested during the night. If the breakfast
consists of only fruits and a glass of milk, then it is completely
digested in 45 minutes. So, you have an empty stomach after 45
minutes. On the other hand, if you eat fried mutton or deep fried
paneer that takes around six hours or more to get digested, then
you have an empty stomach after that period and so on.
Q13. Can I have corn silk tea just before sleeping?
Yes, there is no harm in having it just before sleeping. You can
have it any time.
Q14. Can we add some salt to corn silk tea to make it taste better?
You can add salt or fresh lime if taste is important to you, but do
not add sugar.
Q15. Can we eat the leftover parsley after making the tea?
You can use the residual remains by grinding and filling it in
chapatis. However, it has no nutritional value left as all the nutrients
have already been extracted in the tea.
Q16. Should the corn silk tea be warmed again after refrigeration?
Yes, it can be warmed. Temperature does not affect medicinal
properties of the tea. However, it should not be refrigerated for more
than a day or two.
Q17. Can pregnant women do a Kidney Cleanse?
Yes, they can start with half of the regular dosage. Breast feeding
mothers can do it with regular doses.
Q18. I am suffering from calcium deficiency. Can use of calcium
supplements during Kidney Cleanse help me?
As a naturopath, I believe that for calcium deficiency, the patient should not
be given supplements as these supplements are not absorbed by the deficient body.
Rather, efforts should be directed toward improving absorption of calcium in the body.
This sounds difficult, but it is the most practical and beneficial way. It
can be achieved easily with a Kidney Cleanse, Liver Cleanse, Mud
pack therapy and green vegetable juices.
Mud Therapy is being used by people to treat diseases since
ancient times. It is believed that the earth has healing powers, which
are refreshing, good for treating skin diseases, stomach trouble,
kidney disorder, gout, arthritis, asthma, rheumatism, and gynaeco-
Mud is an important element of nature. It contains important
minerals that have positive effects on human health. The material
used for Mud Therapy is mostly clay, taken from 4" below the surface
of the earth. It can be used as a pack, or as in bath. Mud can absorb
toxins from the human body and is therefore, very useful in preventing
It is also known for its healing properties and helps in cooling and
relaxing the body as it can hold moisture for a long time. This involves
frequent application of mud packs, especially on the abdomen, which
helps in removing toxins from the digestive and other internal organs.
Frequently Asked Questions
How much quantity of corn silk (maize-hair) should a patient take?
I encourage self-medication. You can arrive at the best suitable quantity and frequency for your body through
experimentation.Sometimes corn silk tea causes very mild pain in the stomach (3% of patients). Do not take any
medicine and bear the mild discomfort. The pain will subside without any medication in about an hour or two.
This is caused due to hyperactivity of the nephrons during the cleansing process and is no cause for concern.
Parsley and watermelon seeds do not cause any pain but their cleansing effect is also lower.
How much quantity do you take for yourself, Dr Saxena?
When I started this treatment 10 years ago, I used to take 500 grams of fresh corn silk or 50 grams of dry corn
silk or 500 grams of parsley or 100 grams of watermelon seeds each day, for five days. Now I take 50 grams
of dried corn silk or 500 grams of parsley or 200 grams of watermelon seeds with skin for one day every month.
This procedure makes about two litres of medicinal tea.
Can we store the tea, as prepared above, in a refrigerator?
Yes. It is alright to store the mixture in a refrigerator for two-three days. Warm it if you wish, at the time of drinking it.Temperature does not play any role in the effects of the medicine in the treatment.
I am not able to find corn silk in sufficient quantities in the market due to off season conditions. My stored corn silk
has developed a fungus. Can I still use this contaminated corn silk?
The medicinal properties of this fungus affected dried corn silk do not change. It can be used just as well, with
the same results as fresh or dried corn silk. Keep the corn silk under the Sun for a few hours. Then follow the same
procedure as outlined earlier, for the preparation process. If the corn silk has been stored without drying or in wet
conditions, it turns black and gets spoiled, then it should not be used. Hence, you should keep the corn silk under
the Sun occasionally, so that it remains good for use.
Can I use all the three ingredients, i.e. parsley, corn silk and watermelon seeds together?
No. They are to be taken separately. Any one of them is good enough for the treatment. You may use another
option after a few days.
After following your therapy, why do I experience increased bleeding during menstruation?
This may happen to a few ladies. Treat it as a good sign caused due to cleansing. You must have felt better in
your premenstrual syndrome and have experienced much less abdominal pain. As soon as the toxins that have
accumulated in your body are expelled, your condition will improve and you will feel better in a day or two.
I got tremendous benefit after one Kidney Cleanse but after a week’s period, I am facing the same old problems.
Sometimes the old problems manifest themselves again but if you monitor their frequency and intensity, they
occur at much lower levels after the cleansing. Secondly, you are continuing to live in the same polluted environment
and eating cooked food, so do the cleanse again and you will improve further. You will notice instant
improvement in backache, headache, general freshness level, the duration and quality of sleep.
What is the best time to do Kidney Cleanse?
Kidneys get an opportunity to function more efficiently when the stomach is empty and the body is most relaxed
in a lying down condition. This happens after midnight. I keep a litre of corn-silk (or any of the other option) tea
near my bedside at night. If I happen to get up by chance at 2-4 am I drink this and go back to bed. This procedure
results in the best effect for me.
