Charles Darwin published The Power of Movement in
Plants -- on phototropism and vine behaviour -- in 1880, but the
concept of plant intelligence has been slow to creep into the
general consciousness. He also did some experiments on plants with
homoeopathic remedies. He did not call his experiments homoeopathic,
for that would have been scientific suicide in his day. We know it
is little different today, as many are opposed to homoeopathy
through ignorance. Darwin was experimenting in a scientific manner
when he did his experiments on plants.
He did some very interesting experiments with
Drosera or Sundew, a flesh-eating plant, well known today. He
discovered that however much he reduced the dose of the substance he
used, salt of ammonia – prepared according to the homoeopathic
method with dilution and succussion – the effects were always
visible in the plant. He was quite astonished by these effects and
their consistent appearance with every new dilution. He compared the
substances pheromones, which a dog can smell from a great distance
in the case of, for instance, a bitch in heat.
His frame of reference was the molecule – then the smallest
known particle of matter that was able to show particular
characteristics. He did not realise that the doses he prepared no
longer had any molecules in them, while still being increasingly
active. It stimulated the glands and the plant’s tentacles and
caused the plant to turn inward. Avogadros’ limit may have been
known to him. In 1903 he wrote to the well-known physiologist Prof
F.C. Donders of Utrecht Netherlands, that he observed 1/4,000,000th
of a grain of the salt had a demonstrable effect on Drosera. Here is
what he said about his experiments:
"And that the 1/20,000,000th of a grain of the crystallised salt
does the same. Now I am quite unhappy at the thought of having to
publish such a statement. The reader will best realise this degree
of dilution by remembering that 5,000 ounces would more than fill a
thirty-one gallon cask or barrel and that to this large body of
water one grain of the salt was added – only half a drachm or thirty
minims of the solution poured over the leaf. Yet this amount
sufficed to cause the inflection of the leaf. My results were for a
long time incredible, even to myself and I anxiously sought for
every source of error. The observations were repeated during several
years. Two of my sons, who were as incredulous as myself, compared
several lots of leaves simultaneously immersed in the weaker
solutions and in water and declared that there could be no doubt as
to the differences in their appearance. In fact, every time that we
perceive an odour, we have evidence that infinitely smaller
particles act on our nerves. Moreover, this extreme sensitiveness,
exceeding that of the most delicate part of the human body, as well
as the power of committing various impulses from one part of the
leaf to another, have been acquired without the intervention of any
nervous system."
(Darwin The Power of Movement in Plants 1875)
He also demonstrated that Drosera is not sensitive to just any
substance. He tested several alkaloids and other substances that
have a powerful effect on the human and animal body, which possesses
a nervous system, but that had no effect on Drosera. He decided
that:
"The power of transmitting an influence to other parts of the
leaf, causing movement or modified secretion or aggregation does not
depend on the presence of a diffused element allied to a nervous
system."
(Darwin The Power of Movement in Plants 1875)
He thus confirmed the homoeopathic consensus that living systems
react only to those substances that are in harmony with their own
pattern of energy.
