The Peregrine Falcon (Falco peregrinus)

Falco peregrinus materia medica and complete drug picture of homeopathy remedy Falco peregrinus . Learn all the signs and symptoms of homeopathic Falco peregrinus by Siegfried Letzel.

What changes may arise with a prover in a remedy proving if a new remedy is taken? The symptoms – will they have something in common with the source or will there be no relation?
The remedy proving of the Peregrine Falcon has been conducted by Misha Norland at The School of Homeopathy in 1997. What I intend to do in this article is to examine if the symptoms noticed by the provers have anything in common with the living animal. In other words, is it possible that a homeopathic remedy is able to project characteristics of a living animal to a human being?
Peregrine Falcons are roaming nearly all over the world, inhabiting not only the temperate zones of the globe, but also the tundra around the North Pole which they have to leave each winter “peregrining” southwards, touching all northern countries of Europe, Asia and America. In Africa they can reach eastern Sudan. They have been seen in Southern Asia and in Central America. During their migrations they are easily strolling 1000 km, that is about 620 miles a day. Without great effort they are able to cross the Mediterranean Sea within a single day. Some species of Falcon cross vast oceans in a single flight. A Peregrine has been spotted on a ship more than eight hundred miles from the nearest land.

Peregrine Falcons are courageous, strong and extremely agile birds provided with dreadful weapons. When they catch their prey, usually the victims are stabbed to death or strangled up in the air, or very heavy birds are tortured in the air and then killed after they plunge to the ground.

Their flights are extremely fast with hasty beats of wings, most often close to the ground. When hunting a victim they are flying with such a fabulous speed that spectators find it difficult to estimate it. One only can hear a roaring of wind and is viewing an object falling down, unable to recognize that it is a falcon. The Peregrine Falcon dives so fast that if it grabbed the victim out of the air with its talons it would break its own legs. Instead, the hunter hits its prey with its strongly muscled chest, the prey falling unconscious. Only in the spring they elevate to inestimable heights.

They are very shy and careful. This is the reason why they go to rest only late in the evening. In the deserted tundra, they get out of way of approaching hunters, whereas in bigger cities, they are of an amazing brazenness, which is of striking contradiction to their common habits. This shows that they can easily adapt to changing environments.
The number of Falcons has fallen dramatically since the mid 1950s. In England, the population in 1961 was 68% of the pre-war level and it fell further to 56% in 1962 and 44% in 1963. The decline was a worldwide phenomenon. Falcons, which had once been numerous were now extinct in the vast forests of Eastern Europe and had completely disappeared from the eastern side of North America. There were indications that pesticides had a role in this decline. In England, after restriction of pesticides in 1981 the numbers were up to 90% of pre-war levels. In North America and Eastern Europe they were completely wiped out.

Falco peregrinus is the homeopathic remedy produced from the Peregrine Falcon. A small piece of feather and a sample of blood were taken from Nesbit, a captive bred Peregrine Tiercel, 2 years of age, to produce the remedy.
All information on the remedy-proving have been taken from:

You will read short statements on the Peregrine Falcon taken from different reliable sources (in italics). Each statement is followed by observations of provers after having taken the remedy.

Breeding habitat for Peregrine Falcons was historically restricted to natural cliffs, especially those near water. …generally favouring wetlands.’

‘Went to look at a hill, felt that I was on top of the world. Felt optimistic about moving.’
‘By the sea. Strong emotional response to looking at the sea; the waves and the sun reflecting off the water. Felt like crying. Much stronger response than I’ve had in the past.’
‘My feeling welled up in me and I rushed off into the night with a sleeping bag and spent the night in my car on the moor.’
‘There needs to be more freshness and more air and space around.’

…but smokestacks and the support structures of bridges are also used by many’

‘Have noticed when I blow my nose it’s black and dusty – a bit like when I lived in London, with all the traffic and pollution.’
‘Black stuff when I blow my nose, still, like soot. Nose is quite dried up. Blowing it much less than usual, but always sooty when I do…’

The falcon eyesight is 8 times better than human eyesight and can spot a bird flying 1000 feet below. They have very good eye sight ~ they can spot a meal up to a mile away.

‘Upon opening my eyes, Vision brighter and more clarity.’
‘Vision clearer, brighter’
‘Vision quite clear – more sharp clarity than normal’
‘Everything felt very sharp visually’
‘Vision really sharp – kept looking at some bright yellow flowers outside.’
‘Everything still sharp (vision) – it’s a bit like being a child again, and seeing everything super-sharp and bright.’
‘Sharp, outlines seem quite definite. Eyes getting caught by bright colours more than usual.’
‘People said I had a “faraway look in my eye”.’
‘Vision sharper’
Eyes feel shiny, looking outside, things seem sharper, clearer.’
Their eyes are black
‘People at the restaurant observed that I looked ‘spaced out’, and that my pupils were so enlarged that they could not tell my eye colour.’

1998 – The pair nested again in the same Atlanta location, but both young died of trichomoniasis, a protozoal infection of the mouth and throat usually caused by feeding on infected pigeons or doves.

Author’s Note – Mouth infections are common to falcons. It is a disease called Frounce, a mouth- and throat-infection caused by the protozoan Trichomonas gallinae. It is a widely spread disease for falcons and hawks and is caused by eating infected birds of prey like pigeons.

‘Lots of mouth ulcers, on tongue and inside bottom lip.’
‘Mouth ulcers top left, and bottom right coming on. Dragging me down. Sharp pain, better cold, better clean mouth, worse chocolate, sweet.’
‘Under tongue, fleshy bits sensitive, aware of it – ulcer? – a bit red, slightly swollen.’
‘Skin under tongue (frenulum) has painless ulcer…’
‘Front right lip and back right few mouth ulcers.’
‘Mouth ulcers very bad, speech difficult, depressed.’
‘Ulcers worse, new ones. I’m pissed off with this, painful.’
‘Throat – a feeling like going to be sick – …’
‘Throat feels as if it’s going to get sore, sensation reaches up into back of nose…’
‘Throat worse all over on swallowing…’

The birds supposedly get all the moisture they need from the food they eat.

‘Not thirsty, normally drink a lot of water, today much less than normal.’
‘Drinking consciously today. I experience thirst but don’t necessarily want to do anything about it.’
‘I haven’t been drinking any water. I usually drink pints of water a day, but I haven’t wanted to.’
‘I notice that I’m not drinking in gulps even when very thirsty, sipping only.’
‘I’ve not been so unthirsty, except when I had the sore throat. If I did drink my normal quantity of water, I found I needed more visits to the toilet.’
‘Don’t want my tea…’
‘No thirst.’

The legs end in long toes with strong hooked claws.

‘My nails, which have always broken and flaked, had become stronger.’
‘Desire to grow nails long. Grew very long and strong. Have not had them long for about six years and used to be much softer and flakier.’
‘Nails have been much stronger.’

…Tissue studies of dead birds and of the addled or broken eggs that were now so common seemed to indicate that pesticides had had a role in this decline (of population).

‘Felt overwhelmed by work, it truly is an awful toxic place, and we are all being poisoned by it.’
‘Fear of being poisoned.’

The Peregrine Falcon is widely renowned for its incredible speed. Estimates vary, but commonly cited top velocities are in the range of 290-320 km/h (180-200 mph), achieved only during the characteristic swoop (hunting dive)…the Peregrine Falcon is the fastest creature on earth.

‘Drove back from the party (had some wine but not so much) quite fast but well, changing speed as necessary. It seemed faster to the others in the car than to me.’
‘I had difficulties driving. I felt quite chilled out about driving, normally I would get stressed out.’
‘I drove home that evening in a record time of 1hr 10 min, a journey which usually takes me 1hr 30min. I drove at high speed, I was aware of the speed but I didn’t care. At one stage I spotted a police car in my mirror, fully aware that I was well over the speed limit, I carried on. I remember thinking, well I would be done for that and it would be a shame since I have never had any endorsement on my licence. Nevertheless I didn’t ease off the speed and thought it would be OK and it was, the police car left the motorway before they got to me. I was aware on my journey home that my driving was somewhat careless and that if I was not more careful I would have an accident, but it didn’t stop me.’
‘Was very speedy.’

When it dives, the Peregrine Falcon takes the risk to get smashed. There are examples, when bumping into branches of a tree the Falcon fell unconscious or even has been killed.

‘Picked up some students from Bristol. On the way back a confusion of lanes resulted in having to avoid a van. What was noticeable retrospectively was how I didn’t get emotionally involved: there was no nervousness where normally there would have been.’
‘Erratic driving, P’wah that was close, but it didn’t matter.’
‘Following the proving, on the same day, I did find myself in a state of care free. Nothing was a problem and whatever happened to me I would handle it. I feel very free-spirited.’
‘Went out by myself – feeling very good, pleased with myself, I walked out on the dam on the stream without a thought, after a few minutes I noticed how precariously I was perched and thought quite calmly, “You’d break a leg if you fell off here”, but I didn’t go back immediately.’
‘Drove to party with others – “How can he drive like this?” Thought about having an accident we seemed to be going so close to other vehicles, but I was only mildly concerned as I felt so at ease. Thought an accident would be “somewhat” of a problem to explain.’

I’ve got to admit that when I started this approach, my intention was to find parallels, which may indicate that there was a successful transmission of information. Other notes of the provers I was not able to bring together with the Peregrine. One reason might be that I only used short reports on the Falcon not stating deep details on it. Another one might be that there are no more similarities at all. Maybe one of our readers would like to get deeper into this subject matter. I will be glad to learn from your findings and would be pleased to show it to our community.
What do you think? Can you see the parallels? Do you think the parallels are not so obvious? Let me know what you think.

The Peregrine Falcon – what a unique living being.
Falco peregrinus disciplinatus – what a unique homeopathic remedy!

  • A client contact me requesting an antidote to an incorrectly prescribed Falco peregrinus disciplinatus. Do you have any suggestions?
    Thank you.

    • Kate: Declare your interests in the pharmacological industry, financial or otherwise. It is certainly noteworthy that you found such an “obscure” article to ridicule.

  • Taken Falco peregrinus. I did get a lesion in my lower rear gum. I do feel a bit more care free in my interactions with people. Paul

  • It seem’s this is my remedy.
    Is there a homaccord for this remedy?
    I currently have a bottle in high potency (can’t remember what) which seems to work 🙂


  • I’m currently taking it and it’s been incredibly effective at alleviating a broad range of different ailments. It’s my first introduction to homeopathy and I’m very impressed with the results so far.
    Some of the peregrine falcon’s traits sound quite like me, although I can’t say that I feel like I’ve exhibited these characteristics more strongly since taking the remedy.
    Is the point of this article to suggest that:
    a) When a patient takes the peregrine falcon remedy, (in addition to it hopefully treating their ailments) it also has the curious effect of giving the patient more characteristics similar to that of the bird, peregrine falcon?
    b) Those people likely to develop symptoms which would benefit from being treated by the peregrine falcon remedy are typically the kind of people who are already likely to be similar in characteristics to a peregrine falcon bird?

    Siegfried: I may be misinterpreting this article entirely, but I get the impression that you’re suggesting a.) I’m not sure it resonates with my experience so far, but b) seems to make some sense to me!
