Named Issues
Flowering (7)
Frost with 503 (262)
General Appearance
To lift nitrogen-502, 503, 504, 505 evening; 505, 506, 507, 508 morning. (7)
The nettle follows the work of the chamomile. If the chamomile has brought life into the soil and has supported the part of the plant linked to water, the nettle brings the plant the impetus to overcome the vegetative stage and to rise vertically. So if the plant shows signs of the problems caused by excessive earthly vigour (excess of humus, of water, or of manure) nettle is potentially able to bring remediation. (250)
The nettle can be compared to a conductor who directs all the instruments so that they unite their voices to produce a sublime harmony. (250)
... it brings verticality, [and] gives structure (250)
Stem/trunk and bark - capillary system
it frees the soil from the excessive presence of iron ... [which would] hinder the rise of sap, which cannot reach and feed the ... top of the plant. (250)
For vegetative growth-503, 504 evening, 504, 508 morning. (7)
... it brings order to the vegetative force and pushes this to rise towards the top of the plant where they will support the nutritional value, transforming its impulse into quantity and quality. The rise of lettuce as it moves to flower and the lifting of wheat are examples of the forces of nettle, which can then be used as a remedy when these developmental stages are deficient. (250)
We will see that the nettle, as well as bringing order in the metabolic sphere, carries the impulse to verticality and with that the transition to flowering. (250)
If you want iron, phosphorus, magnesium and the traces for leafy growth, 504. (7)
To induce flower & fruiting-504 evening, with 506 & 507 next morning. (7)
Generative organs
To induce flower & fruiting-504 evening, with 506 & 507 next morning. (7)
On September 6, 1993, LA Rotheraine requested some help... he had overdone his applications of BD501 and BD507 which he had used in combination in more than 5 different applications during the growing season. While his fruit set was indeed impressive one serious side effect was that the plant was losing leaves. I suggested he water-in the plants with a strong dose of 504 and 505 in combination... he stirred one unit each of 504 and 505 together for 20 minutes in 6 gallons of water and treated each plant with this generous quantity of medicine. He followed with a second treatment a few days later.... the plants managed sufficient leaf regrowth. A few days later a killing frost his the garden which wiped out the garden except this tomato. We felt obliged to try this ourselves and treated several pairs of plants with the 504/505 potion... we experienced a totally killing frost during the night following the mid-afternoon dosing ... it was quite clearly apparent hat the treated plants withstood the freeze far, far better than the untreated plants ... and the treated plants were still growing quite healthily three weeks after the initial frost despite several additional frosts. (262)
Vigorously stir 1 - 2 ml in 3 litres of hand warm rain water for 5 minutes and leave for 24 hours. Use as a seed bath for barley. ... germination is faster. Growth is improved and compared to untreated controls these plants prove healthier and give better yields. They are able to cope better with poor weather conditions and develop a stronger and more extensive root system. (42)
Notes and Academic Papers
This preparation will work between the astrality and the etheric body, with an emphasis on the astrality side of the equation. It encourages teh harmonious workings of the astrality. (48)
504 has an especial influence on the quality of the flavour (1041)

Effect on Soil -

Soil characterisation
Iron pan (44)
Soil structure (294)
Soil surface
I would normally be inclined to make a stinging nettle herbal ferment and apply that at 10 to 20 litres per hectare. Nettle has a wealth of silicon and calcium with half as much phosphorous as either-which is the proportion commonly found in rock or colloidal phosphate. But did you know that all these phosphate ores contain fluoride? Florida colloidal phosphate is the richest in fluoride, and is the one in Beddoe's book, but stinging nettle runs something like 7.3 ppm F, the richest in the herbal kingdom. In biodynamic circles valerian is generally thought of as the phosphorous prep, but time after time I've seen the BD 504 give a phosphorous response in the vegetative realm. Great stuff.

Top soil
.. will on the one hand support the activities of 502 and 503, and on the other confer on manure and soil the ability to deal with matter and forces rationally and attune themselves specifically to the crop grown at the time. (34)
It seems strange that a plant which itself contains so much iron might liberate soil from its excessive iron, but it's not so odd if we think that the soil iron is mineral, while nettle is a plant. Therefore nettle brings an impetus of vegetalisation to the mineral iron thus bringing it 'into movement' and the nettle then transmutes it. (250)
If the humus has excesses the nettle within 504 is capable of putting it into order. (250)
... gives structure and puts order in the soil's organic matter. (250)
504 is one of the best preps to open up heavy clays and build humus, preparing the soil for nitrogen fixation. It improves the soil's porosity, unlocks micronutrients and protects against anaemia. (294)
Sub soil
.. an iron regulating effect. Many soils througout the world contain a large amount of iron, which cements the particles together to form what is know as 'iron pan'. The nettle preparation helps to break up these soils, releasing the iron. (44)

Effects on compost and manure -



Ammonia (29)
Heap surface
Inner heap
Abele (1976) showed that nettle preparation on its own, while not effecting the total nitrogen content of the material, reduced the ammonia levels. (29)
Together with the oak bark preparation .... this preparation is in the position corresponding with clay. But only the Nettle is put in the middle of the heap just to underline its particular function to restore order in all processes of the compost or manure. (250)

BD 504: Works with calcium, proteins, magnesium, iron and phosphorus in energy transactions. Works with chlorophyll and haemoglobin as well as other enzymes and hormones. Also works with silicon. (7)
504 ... brings about a special kind of transubstantiation whereby the earthbound substances of potassium, calcium and iron gain properties that approximate those of nitrogen. Medicinal plants like yarrow, chamomile and stinging nettle have the capacity, through the strength of their etheric body, to release the physically dense substances of potassium and calcium from their imprisonment in form and bring them into movement. The substances of potassium and calcium by this route become ‘like nitrogen’ in that they become bearers of soul forces.... it is precisely this qualitative relationship referred to in yarrow, chamomile and stinging nettle that enables the hydrogen to dissolve the structure that binds potassium and calcium and release the astrality congealed within. It is a process of transubstantiation through which the boundaries set by nature are transcended.... It can only serve the good if it is also accompanied by a great soul transformation in the human being. Where this doesn’t occur it will cause destruction. (1565)
