Trituration proving
The giant green anemone is one of the most stunning tide pool animals of
the Pacific coast. Color of the animal varies
depending upon exposure to sunlight. Individuals living in high shade may be
almost grey in color whereas those living in areas
exposed to bright sunlight are a striking brilliant fluorescent green. Coloring of individuals ranges from jade green, olive green
to bluish green. The oral disk, uniform in color and
lacking radiating lines, is broad and flat, and surrounded by haphazardly
arranged, short and thick tentacles of similar color.
At the center of the oral disk there is a prominent
single orifice which serves the animal for both intake of food and elimination
of waste. The exterior of the anemone’s column is a dark green to brownish color and
is velvet-looking in texture. Compound irregular tubercles, called verrucae, arranged randomly on the columns surface produce
the velvet-like effect. The verrucae have adhesive
properties and the anemone’s column is often covered with bits of gravel and
shells which protect against dehydration. Size can be up to 30 cm (12 inches)
in diameter across the crown, and up to 30 cm in length.
Subjective descriptions of these sea creatures liken them to flowers,
particularly because of the beautifully colored and
tentacle-fringed oral disk. Anthozoa, the taxonomic
class which includes sea anemones and corals, is a name derived from the Greek
meaning ‘flower animals.’ The animal’s common name, anemone, is also the Latin
name for a genus of flowering plants in the Ranunculaceae
family. The flower-like appearance of giant green anemones is only suggested
when the animal’s oral disk is open and exposed. When the animal contracts,
thereby withdrawing its oral disk and tentacles to assume a defensive posture,
or when it is prostrated due to exposure to air, all descriptions of beauty cease,
and instead most observers describe them as looking ugly or even repulsive.
Coloration:
This sea anemone produces greenish fluorescent pigments that give it its
striking color and that afford protection to the
single-celled green algae species (the algae themselves are a light brownish color) which live within their gastrodermal
tissues. Giant green sea anemones might therefore be more truly termed
‘plant-animals.’ There is a true symbiotic relationship that exists between the
anemone and the algae (usually zoochlorellae by
itself or with zooxanthellae). The algae, tiny dinoflagellates, gain protection, carbon dioxide and
reliable exposure to sunlight from the anemone, and in return the anemone
receives oxygen, a byproduct of the algae’s
photosynthesis, and trace amounts of nourishment in the form of glycerol,
glucose and alanine. Studies have shown that giant
green anemones living in low light conditions, in which their algae partners
languish, will lose weight faster under poor food conditions than algae living
in good light situations.
Feeding and Prey Items:
Heartily carnivorous yet non-motile, this animal is a patient feeder.
When comfortably submerged in its salt water environment the giant green
anemone opens up its oral disk and tentacles and simply waits for its meal
opportunities to arise. The anemone has access only to prey that swim, crawl,
fall or otherwise come in contact with its tentacles. Prey for the giant green
anemone usually consists of detached mussels, crabs, sea urchins and small fishes
but this species will also consume small crustaceans and a variety
of other organisms that contact its tentacles.
Common sea stars, Pisaster ochraceus,
are a major predator of mussels and in the course of their own feeding they
often dislodge mussels which become a more available prey for any nearby
waiting anemones. It is speculated that anemones actually rely on the predation
activities of sea stars to loosen and dislodge mussels for their own
consumption. Not to be considered solely an opportunistic feeder, this anemone
can of course also capture its own prey.
Once within range, mechanoreceptors alert the anemone to the vibration
of its prey so that upon tactile stimulation stinging nematocysts are
discharged from the tentacles. Hundreds to thousands of nematocysts bombard the
prey, injecting a paralyzing toxin. The stunned prey is then captured as the
anemone’s tentacles bend and close, ultimately transferring it to the gastrovascular cavity via the mouth at the center of the anemone’s oral disk.
Prey is swallowed whole (fins, spines, shells and all). The gastrovascular cavity functions both in digestion and the
circulation of nutrients around the body. Undigested material – shell,
cartilage etc., are excreted back out of the cavity via the animal’s single
orifice.
Predators:
Some species of nudibranchs (e.g. Aealidia papillasa) and snails
(e.g. Eitanium tinctum)
feed on the anemone’s tentacles. Also, some types of sea stars including the
leather star, Dermasterias imbricata,
sea snails and sea spiders (e.g. Pycnaganum stearnsi) feed on the column.
Low tide & Desiccation:
Many sea anemones reside in tide pools where there is always at least
some salt water, but they can also survive in surge channels and other
locations which expose them to air at lower tides.
They do so by withdrawing their tentacles and contracting their columns.
This adaptation reduces the surface area exposed to evaporation, and is
effective for only certain degrees of exposure.
Reproduction & Life Span:
While many anemone species reproduce both sexually and asexually, Anthopleura xanthogrammica
practices sexual reproduction only. They are broadcast spawners.
Sexual reproduction takes place in the late spring and early summer. Males
release sperm which stimulates the females to release eggs. Eggs and sperm are
ejected via the single orifice (mouth/anus) of the anemone. Giant green
anemones rely on ocean currents and water flow for
the mixture and dispersal of gametes. Potential dispersal is over long
distances. Adrift at sea, those eggs which are fertilized develop into planula larvae (flat shaped, ciliated, free swimming
embryo). Each planula eventually settles and gives
rise to a single new anemone. Adult size is usually attained at 14-15 months of
age. Anemones are known anecdotally to live to be “monstrously old.” Certainly
an age of 30 years is common, and since mortality of adults is very low, the
estimated ages of 500 plus years postulated by some researchers seems possible.
Structure, Anatomical & Physiological Features:
Giant green anemones are animals of typical polyp structure, and have
radial symmetry based on the oral-aboral axis. Their
basic structure is that of a cylindrical sac. They are attached to the ocean
bottom by an adhesive foot, and have a column shaped body ending in an oral
disk.
Simple tubular tentacles are arranged in ringlets around the oral disk.
Between the external epidermis and the internal gastrodermis
cell layers, the body wall is comprised of a gelatinous matrix called the mesoglea. Some connective tissue and muscle fibres are
contained within the mesoglea.
Ciliated grooves on the oral disk allow water currents to enter the
anemone’s coelenteric cavity, and cilia throughout
increase this flow, creating a hydrostatic skeleton which supports the anemone
in an upright columnar position. Deflation of the anemone’s body is muscularly
controlled but inflation of the hydrostatic skeleton is not.
The pedal disk or foot at their base allows the animal attach to rocks
or other hard substrate.
Change of location is possible by slow repositioning of the foot, but
most anemone movement involves only changes in their body shape and not changes
in location. Body movement is achieved through muscular contractions, and when
disturbed by a predator or other aggressor the anemone contracts, withdrawing
its tentacles and oral disk. The giant green anemone has a more prominent
sphincter muscle than many near relatives.
Anemones are the simplest animals to have nerve cells arranged in a
nerve net, a primitive nervous system without centralization or a true brain.
This primitive nervous system is limited in scope, but does allow for
mechanical reaction to stimulation. Anemones are also the simplest
animal to have sense organs which include statocysts,
organs for equilibrium, and ocelli, photosensitive
organs.
Their gastrovascular cavity has a single
opening that serves as both mouth and anus, and the animal has no excretory
system. Digestive enzymes secreted by the gastrodermal
cells lining the gastrovascular cavity promote
extracellular digestion. To complete digestion the gastrodermal
cells phagocytize the partially digested food
particles and therefore digestion is then completed within the cells.
Gas exchange, absorption of oxygen and elimination wastes including
carbon dioxide and ammonia, is accomplished at a cellular level in the gastrodermis and epidermis. There are no specialized organs
or body surfaces for gas exchange or the elimination of wastes.
Anemone tentacles are laden with cnidoblasts,
the specialized stinging cells which produce nematocysts. Cnidoblasts
consist of a toxin-filled vesicle and an external sensitive hair that connects
to an inner filament. When the external hair is stimulated chemically or
mechanically, it triggers explosion of the cnidoblast
cell and the propulsion of the toxin-laden inner filament.
These tiny weapons burst out at a velocity of 2 meters per second and at
40,000 times gravity.
Prey articles can be stung by hundreds or even thousands of individual
nematocysts at a time.
The toxin is a mix of compounds including neurotoxins that serve to
paralyze prey and effectively repel some predators. Some research suggests that
the nemoatocysts and the bursting of the cnidoblast cells themselves create a suction action which
also helps in the capture of the prey item.
Several sea anemone toxins have been isolated and studied by man. One of
these toxins derived from the giant green anemone, a polypeptide chain known as
Anthopleurin-B, is a potent peptide heart stimulant.
Other anemone proteins are also isolated and known as effective sodium channel
inhibitory toxins.
Proving of Anthopleura xanthogrammica
the giant green (sea) anemone. The anemone family of invertebrates named the Cyndarians formerly Coelenterata.x (Gr. for hollow intestine) have a single body
cavity providing digestive, excretory and respiratory functions.
When they are exposed to air for a reasonable time period, they adapt by
withdrawing their tentacles and contracting their columns, which
reduces the surface area exposed to evaporation.
This idea of withdrawal is seen in different ways in the proving, for
instance one prover said, “I feel at a much lower
level as a person. My thinking, emotions and intuitiveness is not coming to the
surface.
Another prover reported this feeling:
Insulated from others on outside, in own world on inside, numbed, a wall
between”. This wall between thinking and feeling or sensing and no senses was
expressed elsewhere:
“I like to sense, feel and be 100% where I am, and now that's taken away
(by a numbness taking over part of his brain), there's no way you can be”.
Follows happened on our trituration weekend:
C1 and C2: a marked unwillingness or lack of ability to communicate and
to connect with other people. We were in a dull trance, as though floating in
our own inner world completely disconnected from the world outside. We had a
strong desire to be alone. We felt tiredness, weakness and a lack of energy
along with confusion about time and location. In general, it was a gentle
state, in which we surrendered to a dull nothingness.
There was fear of sharp and pointed objects; even the rectangular
corners of a house seemed to be painfully threatening. We stumbled when walking
and had difficulty writing, due to awkwardness in the use of our limbs.
The lack of connection between the participants in the group was so
extreme, that even in the break everybody did their own thing. There was little
communication, which is very unusual for that kind of an event.
Feelings of sadness and loneliness came with the lack of connection.
Even though the energy felt very soft and gentle most of the time, there
was at times a strong aggressiveness present. There were visions of fire, a
rocket starting, and a cannon with a human inside as cannonball, being attacked
with arrows and spears and even the desire to hurt somebody. These feelings
demonstrated a strong presence of aggressive impulses within this mostly gentle
energy. These polarities of gentleness and aggression also lacked
connection.
C3: the mental level of the process, usually yields some clarity. Not so
in this trituration. The brain fag was complete, our
mental and intellectual abilities gone. There was
no energy, mental dullness and even an aversion to talk at all. It felt
like being alone on a hot summer day, absolutely bored and the sun draining
what energy was left.
We had the desire to be still, not to move, even to stop breathing.
C4: finally brought resolution. In this level we experienced the
extremes brought together. Aggression and self-surrender were no longer
contradictions. Love and sexual aggression felt perfectly in harmony; water and
fire seemed not to exclude each other anymore. The lack of connection and
sleepiness were gone. Heat and sun were comforting rather than draining. “I can
be a flower child in a graceful dance and in the next moment be a warrior ready
to kill. It is all one dance in perfect beauty and selfless innocence.” This was an expression of the final harmony
we experienced.
Summary:
The Giant Green Sea Anemone can help us to connect opposite extremes of
a polarity, to integrate the fire into the water, which before seemed to be
impossible.
In this harmonious state we can bring the masculine spark, the fire, the
aggressiveness into a feminine space of surrender and beauty.
The two energies, which seem to exclude each other, are connected, the
masculine now supporting the feminine. The feminine without the spark of
aggressiveness can
get drained, loses its vitality, its energy. The masculine without the
feminine can end up in destructiveness. Together they create a sparkling
beauty, which is at the same
time gentle and ready to fight.
Overall it is a feminine energy with the willingness to use its masculine
hunter/warrior energy at any time.
Surrendering only to the dance of the waters and waves, to the
mesmerizing and soft rhythm of the tides, the breath of the ocean, can cost us
our stamina and vigour.
If the waters of emotions within us get stuck or rise up in chaotic
turmoil, we would have a hard time coping. We would either collapse
energetically or lose contact with
others and withdraw. Both happened in this trituration.
The energy of the Giant Green Sea Anemone helps us to integrate the ability to fight
to save our presence in the world.
I highly recommend reading Cynthia Shepard’s
introduction to the proving www.homeopathycourses.com/pdf/GiantGreenSeaAnemone.pdf?
The biology of this animal, particularly the mechanism of shooting nematocysts
like poisonous arrows into the body of its prey, sheds light on many of the
experiences of the trituration. None of the
participants knew about these things before C3.
According to our experiences in the trituration,
the patient who would require this remedy, might look like this:
He/she runs a more feminine energy, being very much affected by what is
going on around her, from other people’s words or actions. They would respond
to stress with
the desire to be alone, with withdrawal and some outbursts of anger. Anger
and gentleness would be very much disconnected, the inner disconnectedness with
themselves being reflected in the outside disconnectedness from other people,
from the “real” world. They might have a hard time coping with what is asked of
them in their daily life. This would result in an energetically drained state,
a collapse of vital energy, resulting at first in sleepiness, tiredness, lack
of interest, and later in all kind of physical
problems i.e. increased appetite, leading to overweight etc.
The Giant Green Sea Anemone helps to integrate fire energy into the
predominant feminine flow and gentleness, thus giving it tension, not the tense
rigidity of apprehension but the relaxed ability to “shoot” at any time. This
is possible, even requires one to be “out of one’s ,” because thinking about
fighting would make us tighten up. Yet this creature teaches us to be
completely in tune with the rhythm of life, to be completely relaxed in the
moment, with the fire inside awake, making absolute presence and vigilance
possible, clear awareness of what is going on and the readiness to react
instantaneously and unmistakeably. Anthopleura could
be a deep remedy following an acute prescription of Staph.
The content of the previous paragraph are merely ideas that have to be
proven in our homeopathic practice. I would appreciate it if homeopaths would
document their experiences with this remedy over the next year or two. Cynthia Shepard offered to collect Anthopleura-cases.
Please, if you have any practical experiences, bring them on paper and send
them to Cynthia, so in due time they could be offered to our homeopathic
community.
