On the Use of Potentized Citric acid, Light and Sound in Agrohomeopathy

Citric acid. H2C-COOH – Trituration of the crude substance

CLINICAL – Weeds of all kinds

Citric acid is the main component of the Krebs-cycle, also called the Citric acid-cycle. It enables the chemical transformation of glucose in the mitochondria of the cells, releasing energy. The Krebs cycle or citric acid cycle is a sequence of chemical reactions in which the acetyl portion of acetyl Co-A is degraded to carbon dioxide and hydrogen atoms. (See Pyruvic acid for details of the previous stage of glycolysis)

The citric acid cycle is the third stage in the degradation of the glucose molecule. It is also known as the tricarboxylic acid cycle or Krebs cycle. This is a sequence of chemical reactions in which the acetyl portion of acetyl Co-A is degraded to carbon dioxide and hydrogen atoms. Then the hydrogen atoms are subsequently oxidised, releasing still more energy to form ATP. Below we give the chemical reactions in the citric acid cycle.

Any disturbance or distortion of the citric acid cycle will severely influence plant life, since it breaks into the citric acid cycle and profoundly upsets the glucose transformation and so impairs the plant’s energy. When used as a remedy, if repeated twice in two days, the death of the plant is certain and swift. Citric acid is therefore a first-class weed killer with the additional advantage of not leaving residues. Sunlight, which contains Ultra-Violet rays, destroys any possible residue in less than 48 hours. Generally, its use on weeds does not necessitate waiting, since the remedy is absorbed by the plant’s root system, leaving no possible residue.

Citric acid is the first acid in the cycle, hence its name. It is evident that anything that disturbs this cycle severely affects all processes in the plant. Chlorosis is the first sign of disturbance of the Krebs cycle. This may have several causes, from nematodes to nutrient excess or deficiency, or from what are called pathogens, such as viruses, bacteria or fungi, including pest attacks. However, it is conceivable that a single dose of Citric acid can restore equilibrium. If repeated in a healthy plant it will destroy it, hence it usefulness as a weed remover.

We know from citrus fruit-peels that they leave a bare patch around them and that for some time nothing will grow there. This is an allelopathic* effect, caused by certain acids closely related to citric acid itself, which suppress the growth of other plants. Since we do not want such a prolonged effect, we can reduce the dose to such an extent that no residue will remain – at full sunlight the effect lasts only a few hours, otherwise 24 to 48 hours, depending on the amount of UV in the provided light.

It must be noted that in the citric acid cycle there are 7 different acids involved, making it an octave from beginning to end, which is parallel to the 7 chakras in humans and the 7 tones of the tone-ladder. These in turn have relations to the Periodic Table, where each 8th element has properties similar to the first. It does not make a difference where in the Periodic Table one starts – the 8th element is always similar to the first. Hence the Periodic Table is connected to the octave as well. This octave is best observed in the different Groups – i.e. the elements that are vertically placed.
It seems therefore logical to investigate the possibility of potentising sound – at the different whole notes – to discover what kind of influence these have on the citric acid cycle and on plant life as a whole. Since light also follows an octave – 7 colours of the rainbow – and light does have effect on plants, one fails to comprehend how sound should be void of such effects.

The effects of light on plants is restricted to a few phenomena, as far as investigations have been conducted. Blue caused sickle-leaf in several species, restricting one side of the leaf to develop, while allowing full development of the other side of the central vein.

Yellow caused a dying thistle to do this much faster – within 24 hours it was completely yellow and prostate on the ground. Later repetition on a plant of the same species in full vigour failed to have any significant effect. Red caused the blue flowers of the same species treated to show iridescent colouring, as if they had day-glow paint on them. The Spectrum – made of a mixture of all the colours in the crude – had apparently no effects at all.

To satisfy the curiosity of those who wonder how colours can be potentised, we shall explain our method. A clear-glass bottle receives a coloured cellophane wrap-around, is filled with water and set in the full sun for 3 to 5 hours, depending on the latitude where one is situated. As soon as the time has passed, the resulting product – which actually contains all the colours except the one wrapped around it – is divided and succussed 10 times for each potency, till the 6th potency is reached. This is used to prepare the tank with sprayable substance, by mixing 20 drops per litre and succussing this mixture 50 times. This is mixed with 200 litres of water in the tank and applied on the plants. Results are visible within a few days and can be enhanced by repetition.

It must be kept in mind that only a few tests on a few species of plants have been conducted and that the results cannot be predicted. The risk of damaging a plant remains real, since we have not investigated the effects on any of our food plants. If you try it out, do it on a cheap pot plant or one you do not have particularly much attachment to.

To return to sound as a remedy, we suggest using a Tibetan singing bowl, the tones of which are either flat or sharp, according to our scale of tones. In the 19th Century, it was decided to change the tone ladder and what had up to that time been a C, was lowered in tone, so that the former tone became a C-sharp. The Tibetan bowls maintain the former tone and are thus tuned to the real C. Fill the bowl with water – approximately 0,5 cm from the bottom. Generate the tone for at least 30 minutes. Immediately potentise the water as described under the coulours section above. Apply as explained above and wait for effects to manifest.

* Allelopathy is the inhibition of growth of a plant due to biomolecules released by another. The biomolecules are called allelochemicals.

V.D. Kaviraj is a Dutch homeopath, author, researcher and pioneer in Agrohomeopathy. He is also Vice President, World Homoeopathic Association UK Chapter. He has written textbooks on various aspects of homeopathy including "Homeopathy for Farm and Garden", which is now available in seven languages. The revised and enlarged edition with 376 pages has just been published :


  • Dear Dr Kaviraj, In Australia we have a major problem with pasture infestation with parthenium weed, this is being tackled with chemicals but think problem increasing not decreasing as plants are now flowering and seeding without any significant size- your thoughts please.

    • You might give a try with Juglone or Juglans nigra, which is a seed inhibitor. If those plants are leafy, then the seeds will not germinate, while the grasses should have little problem with it. They are after all already established.

      That said, Juglone may also inhibit the growth of the pasture grasses, but that is a risk you have to take into account. I have not used it on pasture before. Try out on a small plot first and if satisfactory, apply on broadacre.

    • Hi! Pls, how can I ‘Potentise’ the Citric acid. Also, kindly provide a practical guideline on these experiments, I’l like to try these out here in west africa and see the possibility!

      • Citric acid can be bought in the hoimoeopathic pharmmacy.

        At the top of the page is a description on how to use all the homoeopathic remedies for plants. Better is it to use Juglans nigra but always before planting the crop. Wait 48 hours before you plant.

  • Hi Doc! Pls elaborate on ‘potentized’ citric acid. Can this experiment work in the tropics, can it be economically viable? I’m interested in trying it out, pls advice!

  • Citric acid is not the best among the weed control remedies. There are many plants that have proven to be not affected, as my latest research shows.

    So the demands of scientific investigation and negative results demand that I say it is not the best.

    Much better is Juglone, Abies nigra and Abies canadensis, because even in nature these trees have proven their capacity for weed suppression. A recent experiment here in London at a housing estate showed that it is equal to or better at controlling weeds than conventional means, with the added bonus of being non-poisonous.

    So even in the tropics, I would prefer those remedies above Citric acid.

    Chickweed is killed in 48 hours by Phosphoric acid, as many tests have shown. I have not yet conducted enough tests to determine its viability on other weeds, but another trial is underway at the same housing estate in London, to ascertain its efficacy on other weeds.

  • In the mean time, it has been discovered in many field tests that but few weeds will respond to this remedy, even in many repeated doses. The same can be said of Oxalic and Acetic acid and the article on Peruvic acid, till we have gathered more data, on several different potencies.

    Therefore, the results do not match the expectations and this remedy should be excluded from following publications, except as a footnote with the inadequate results that have caused their withdrawal.
