Hecla lava
Volcanic ash (Mt. Hekla) · Hekla lava. · Mineral
Hekla is best suited to people who are rather volcanic in temperament. They usually suppress any anger, but after a certain point they erupt. The remedy is typically used for bone disorders, such as exostosis (benign bony outgrowths) or osteitis (inflammation of the bone). It is considered particularly suitable for treating sarcoma (cancer of the connective tissue) and osteosarcoma (a malignant bone tumor), especially if they occur in the jaw, head, or legs. Glandular swellings, particularly those in the neck, can also be treated with Hekla, as can toothaches.
Key symptoms
- Marked action on the jaws; exostosis and gum abscess
- Difficult teething with nodosities and caries of bone
- Osteitis, periostitis, osteosarcoma, and rachitis
- Facial neuralgia from carious teeth and after dental extraction
- Toothache with swelling about jaws
- Enlargement of maxillary bone; abscess of gums
- Cervical glands enlarged and indurated; bone necrosis after mastoid operation

Face
Ulceration of nasal bones. Facial neuralgia from carious teeth and after extraction. Toothache, with swelling about jaws. Abscess of gums. Enlargement of maxillary bone. Cervical glands enlarged and indurated.
Relationship
Compare: Silica; Mercur; Phos; Conchiolinum--Mother of pearl (diaphysis of bone affected; parts extremely sensitive to touch).
Amphisbæna-Snail-like lizard (great affinity for the jaw bones, worse by air and dampness).

Characteristics
I have chosen the single word Hecla in preference to Heclæ lava, as being simpler and more convenient. The ash and scoriæ of this volcano contain Silica, Alumina, Lime, Magnesia, with some Oxide of Iron. When travelling in Iceland, Garth Wilkinson noticed that the sheep in the vicinity of Hecla had immense exostoses on the jaws. Another effect noticed was the drying up of the milk both in sheep and cows. The finer ash which fell on pastures at a distance, was the most deleterious; the gross ash near the mountain was inert. In cows, post-mortem examination showed the intestines …
