Hydrophobinum (Lyssinum) Homeopathic Remedy: Uses, Symptoms & Materia Medica

Hydrophobinum, frequently referred to in modern homeopathic pharmacopoeia as Lyssinum, is a nosode prepared from the potentized saliva of a rabid dog. Through the homeopathic process of serial dilution and succussion, the original substance is rendered entirely safe and non-toxic, transforming it into a deep-acting energetic medicine based on the principle of "like cures like."

The core theme of this remedy revolves around an extreme state of nervous hyperesthesia—where every physical and emotional sense is painfully magnified. Its primary physiological action centers on the medulla oblongata and the sympathetic nervous system, creating severe reflex spasms, particularly of the throat and respiratory tract.

The Mental and Emotional Picture

A patient requiring Hydrophobinum exhibits a great variety of mental disturbances. A defining emotional trait is intense mental irritability, which can rapidly escalate; a dangerously violent temper is frequently developed. The practitioner will note a distinct inclination in the patient to be rude and abusive, even displaying a sudden urge to bite and strike those around them. Their speech is noticeably rapid, hurried, and filled with impatience.

During pregnancy, women needing this remedy often suffer from strange notions and dark apprehensions. Additionally, patients may present as clairaudient (hearing sounds or voices beyond normal perception) or clairvoyant.

The Defining Characteristic: Aversion to Fluids

The most striking and unusual feature of Hydrophobinum is an exquisite sensitiveness to fluids. The patient exhibits a profound thirst, yet suffers from a spasmodic inability to swallow. Thinking of fluids of any kind—even the thought of blood—brings on severe distress or outright convulsions. Even the mere thought of water is enough to bring on an aggravation.

The sound of running water, or observing the bright surface of water, triggers intense physical reactions. For example, clinical cases of dysentery are noted where severe pain and tenesmus (straining) are triggered simply by hearing water running from a tap.

Extreme Hyperesthesia and Sensitivities

The sensory nervous system is incredibly overactive. The patient demonstrates an exquisite sensitiveness to a breath of air or the slightest draught; even air of an agreeable temperature feels painfully cold. Damp, warm air oppresses them heavily.

They are equally sensitive to bright objects. Looking at something bright, or encountering every little bit of dust, triggers frequent sneezing, mostly early in the morning or late in the evening, feeling as if a coryza (head cold) would begin. When sneezing, the patient reflexively throws their head back. The heat of the sun is entirely unbearable, severely aggravating their condition, and they cannot bear it at all. Furthermore, they are highly sensitive to the slightest touch and to any changed position.

Specific Physical Symptoms

• Mouth and Throat: A prominent symptom is the production of copious, viscid (thick and sticky) saliva.

• Respiration: The patient frequently exhibits sighing and a heavy, sighing type of respiration.

• Female Reproductive Organs: There is a distinct, uncomfortable consciousness of the womb. Symptoms include severe irritation in the sexual organs, severe leucorrhœa accompanied by pains in the back, and prolapsus uteri (prolapse of the uterus).

Modalities (Aggravations and Ameliorations)

Worse From (<):

• Stooping and motion generally.

• Any changed position.

• The slightest touch.

• Riding in a carriage.

• The heat of the sun.

• A slight draught or damp warm air.

• Seeing, hearing, or thinking about running water or bright objects.

Better From (>):

• Bending the head backward (relieves pain in the neck).

• Cold air (relieves the headache).

• Taking a Turkish bath.

• Directing hot steam to a bitten place (relieves the burning pain in it).

Clinical Indications

Hydrophobinum is highly useful in a wide array of specific pathological conditions, including: Hydrophobia and Lyssophobia (fear of rabies), Mania, Convulsions, Tetanus, general Nervousness, and Hypersensitiveness. Neurological conditions respond well, including Sciatica, Neuralgia, Landry's paralysis, Ascending paralysis, Respiratory paralysis, and general Paralysis.

It is also indicated for reproductive issues such as Vaginismus, Prolapse of the uterus, Leucorrhœa, Satyriasis (excessive sexual excitement), and specific issues of pregnancy (convulsions and toothache). Gastrointestinal disorders like Diarrhœa, Dysentery, and Stricture of the œsophagus are covered. Other varied conditions include Fever, Sunstroke, Bubo (swollen lymph nodes), Salivation, Ulcers, pains in Corns, oiliness of the hair, and wounds characterized by too rapid healing.

Comparative Materia Medica

To differentiate from other remedies, note the following clinical comparisons:

• Lachesis: Like Hydrophobinum, Lachesis is worse from the sun, has a bluish discoloration of wounds, exhibits irritability, is worse in warm/damp air, and worse from touch and pressure. However, the late evolution of the symptoms of Hydrophobinum contrasts sharply with the lightning-like rapidity of snake-venom effects.

• Ascending paralysis: Compare with Gelsemium and Conium.

• Respiratory paralysis: Compare with Solania, Belladonna, and Dulcamara.

• Sexual excitement: Compare with Cantharis, Picric acid, and Graphites.

• Intolerance of sun: Compare with Gelsemium, Glonoinum, Natrum muriaticum, Lachesis, and Apis.

• Effects of carriage-riding: Compare with Cocculus.

• Desire to urinate on seeing running water: Compare with Cantharis and Sulphur.

• Convulsions from dazzling light: Compare with Stramonium.

• Consciousness of womb: Compare with Helonias.

• Viscid saliva: Compare with Epiphegus and Hydrastis.

• Hurried speech: Compare with Hyoscyamus.

• Coldness: Compare with Heloderma.
