What is Mygale Lasiodora?
Origin and source. Mygale lasiodora is a large, hairy bird-spider of the tarantula group, native to the forests of South America. In homeopathy the whole creature is used as the starting material, taken through the standard process to prepare the remedy -- entirely distinct from the living animal or any crude venom handling.
Preparation in homeopathy. As with all homeopathic remedies, the material is taken through the standard process of serial dilution and succussion so that the final preparation is highly diluted. What remains is a remedy defined by its symptom picture in the materia medica rather than by any material quantity of the original source.
Historical place in homeopathy. The spider remedies hold a distinctive niche in the homeopathic materia medica, and mygale lasiodora is documented among them (Boericke and the older repertories) for a picture of convulsive, choreic movement and impulsive excitement. Its provings recorded a striking cluster: violent, erratic motion that is dramatically worsened by music and by being touched, with a left-sided predominance of twitching. The spider group as a whole carries a reputation for wild, dance-like, uncontrollable movement -- a thread that runs from the tarantella folklore of southern Europe into the homeopathic proving literature. Because tarantula remedies share this "worse from music" thread, mygale lasiodora is traditionally grouped with its close relations while retaining its own character. The remedy is considered by practitioners chiefly where the choreic, music-sensitive picture stands out in the individual case.
How the remedy is understood. In the homeopathic method a remedy is chosen because the totality of a person's symptoms -- physical, general, and mental -- resembles the symptom picture the substance produced when proved. Mygale lasiodora is therefore not prescribed for a diagnosis such as "chorea"; it is prescribed for a person whose individual pattern of convulsive restlessness, worsening from music and touch, and impulsive excitement matches the remedy's documented picture. This distinction is central to responsible homeopathic practice and to reading this page correctly: the remedy names a pattern, never a cure.
Key Characteristics
- Violent, uncontrollable convulsive movements -- wild, erratic motion that the person cannot hold still.
- Worse from music and from touch -- two of the most characteristic aggravators of the remedy.
- Chorea and St. Vitus dance -- jerking, dancing movements, often with a left-sided emphasis.
- Sexual excitement and mania -- a state of impulsive, erotic, or manic energy.
- Twitching, especially on the left side -- the choreic motion favours the left of the body.
- Restlessness with wild, erratic motions -- an inability to keep still, with unpredictable movement.
- Mirth alternating with rage -- a rapidly shifting emotional state.
- Better from being alone and quiet -- the opposite of music and touch; solitude soothes.
Traditional Symptom Picture
In homeopathic practice, mygale lasiodora is traditionally considered when a person's symptom pattern includes the themes above. The picture is built system by system:
Head
Convulsions with facial twitching and wild, staring eyes; the head and face share the left-sided, jerking tendency.
Eyes
Wild, staring eyes accompany the convulsive and manic states.
Nose
Not a leading feature; addressed within the broader constitution.
Throat
Not a leading feature; addressed as part of the whole picture.
Skin
Crawling sensations and tingling are traditionally noted, a sensory thread beneath the visible restlessness.
Mind
Mania with erotic excitement and violent impulsiveness; mirth that alternates rapidly with rage. The mental state is as erratic as the body, and it is readily stirred by stimulation. The person may laugh without cause, then turn suddenly angry or destructive, with an inner pressure that feels impossible to contain. Sleep is light or absent during the spell, and the impulses -- whether toward movement, speech, or contact -- arrive faster than judgement can check them. This is not a settled mood but a storm of rapidly shifting energy that the individual cannot voluntarily still.
Constitution & temperament
A highly excitable, impulsive constitution prone to wild, uncontrollable movement and rapidly shifting emotion.
Respiratory
Spasmodic breathing with hiccough is traditionally recorded, the breathing catching in rhythm with the general convulsive tendency.
Heart
Violent palpitations accompany the convulsive restlessness, the heart quickened by the same impulsive energy that drives the motion.
Urinary
Not a prominent sphere in the traditional picture.
Extremities
Choreic, jerking movements -- especially on the left side -- with an inability to keep still. The limbs dance and twitch against the person's will. The motion is not the steady tremor of exhaustion but a sudden, flinging, purposeless movement that breaks out without warning and subsides only to return. The left side is classically the more affected, so that a practitioner notes whether the twitching favours one half of the body. Between the bouts the person may be able to sit, but the least stimulus -- a sound, a touch, a demand -- rekindles the restlessness, and the cycle repeats.
Modalities
Better: being alone, quiet. Worse: music, touch, excitement.
Every symptom is read as part of an individual's complete picture. Two people with the same diagnosis may receive different remedies.
Conditions Where Practitioners May Consider Mygale Lasiodora
The conditions below are ones where homeopathic practitioners traditionally discuss mygale lasiodora as one possible remedy among many, selected by the individual's complete symptom picture. Each links to its live condition overview and (where available) its in-depth guide.
Homeopathy individualises; responsible care includes medical diagnosis where indicated.
Common Patient Questions
- "My movements are wild and jerky and music makes it worse -- is this my remedy?" Choreic movement that worsens with music is a classic theme, but only a qualified homeopath can confirm the match, and seizures or loss of control must be evaluated by a physician.
- "I feel restless and impulsively excited -- could mygale lasiodora help?" Manic, impulsive excitement is traditionally discussed; individualised assessment is needed.
- "Touch seems to set off the twitching -- is that relevant?" Worsening from touch is a recognised feature; a practitioner would weigh it alongside your whole picture.
- "Is the left-sided twitching significant?" A left-sided predominance of movement is traditionally noted within the picture; it is one detail among many the practitioner considers.
Potencies
Homeopathic preparations use potency scales indicating dilution and succussion:
- 6C / 30C -- lower Centesimal potencies, traditionally used in milder or more superficial presentations.
- 200C -- a higher potency, traditionally for deeper or constitutionally-matched cases.
- 1M -- a high potency used occasionally in individualised practice.
- LM -- a gentle, sequential potency format for sensitive individuals.
Potency is individualised -- chosen by the practitioner from your constitution and response. We do not advise self-selection of potency.
Dosage
Homeopathic dosage varies by individual: constitution, acuity, potency, and response. The practitioner sets the plan and reviews at follow-up; self-dosing over long periods is discouraged as it can obscure the remedy's effect.
Safety & Precautions
- Pregnancy & breastfeeding: discuss with your physician and a qualified homeopath.
- Children: practitioner-led remedy selection, especially where movement disorders are involved.
- Existing conditions / medications: homeopathy is a distinct system of medicine; keep your physician informed and continue prescribed treatment as needed.
- Urgent care: seizures, loss of consciousness, inability to control movement, or any severe acute symptom -- seek conventional medical care promptly.
Side Effects
- Homeopathic aggravation: a brief, temporary intensification may occur as the remedy acts; judged by the practitioner.
- Stop & consult if symptoms worsen persistently or new severe symptoms appear.
Who May Benefit?
Framed as symptom patterns, not diagnoses: violent, uncontrollable convulsive movements; marked worsening from music and from touch; choreic, left-sided twitching; manic or impulsive excitement; restlessness that will not settle; mirth alternating with rage. Benefit is individual; a matching pattern -- not a disease label -- is what the practitioner assesses.
Who Should Avoid Self-Medicating?
Anyone with seizures, loss of consciousness, or uncontrolled movement; pregnant/breastfeeding women without guidance; infants/young children; people with severe neurological or psychiatric symptoms, or persistent worsening.
