Biotite Mica
(Calcutta Unani College, Adam, 2019) |
A sample of Biotite Mica as used in Tibetan Medicine (Library of Tibetan Works and Archives, Dharamsala, India. Adam, 2006)
|
Mineralogical Name:
Biotite mica, a ferro-magnesium silicate. K (Mg Fe)3 X(Si3AlO11) X (OH)2
Parts used:
Prepared (Bhasma of) Biotite Mica.
Because this is difficult to prepare, and most used in Bhasma (ash) form, it is best bought from a reputable Ayurvedic manufacturer.
Ayurveda uses 'Black' Mica which is the Biotite variety.
Mica is a complex mineral, the main varieties being:
1. Biotite: K(Mg,Fe2+)3(Al,Fe3+)Si3O10 (OH)2 : ‘Black’; also Golden, Brown with Iron and Magnesium
2. Lepidolite: K2Li3Al3(AlSi3O10) (OH)4 : Reddish, pink, purple in color; rich in Lithium
3. Phlogopite: KMg3(AlSi3O10) (OH)2 : Brown, or various colors; Magnesium rich
4. Muscovite: KAl3Si3O10 (OH,F)2 : ‘White’; Colorless, Silvery, White or Yellow-White; there are several varieties of Muscovite:
5. Fuchsite: Muscovite variety; similar composition to Muscovite, but with up to 5% Cr2O3.
Temperature & Taste:
Neutral/Warm. Bitter, astringent, with a post-digestive Sweet taste
PROPERTIES:
Nature: Plates, separable
Color: black-green
Streak: black-green
Cleavage: Perfect
Fracture: Uneven
Luster: Splendent
Tenacity: Flexible
Transparency: Translucent
Hardness: 2.5–3
Specific Gravity: 2.6–3
A piece of Biotite Mica held over the outer zone of a flame will swell to almost double volume and turn from Black to Silvery.

DOSE:
Of the Bhasma: 50–125mg of the Bhasma (125mg is a standard dose), up to 375mg with honey, ghee, Triphala or Ginger juice etc.
NOTE:
Talcum and Mica are closely related minerals. Both are silicates that form in lamina sheets. Talcum is an Magnesium silicate. Mica replaces one-fourth of the silica with Aluminium, making a Magnesium-Aluminium silicate. The Aluminium bonds also contain Potassium cations in Mica.
PURIFICATION:
Mica is only used in Ayurveda after being formed into Bhasma (oxide or ashed medicine).
Before this, it requires purification.
1. Mica may be purified with a variety of substances. It is heated, then quenched 7 times in any one of the following liquids:
i. Decoction of Zizyphus mauritiana
ii. Kanji (Rice Vinegar);
iii. Cow Urine
iv. a strong decoction of Triphala (the 3 Myrobalan fruit)
v. Cow milk
vi. the juice of Eclipta alba.
vii. Lime juice.
viii. decoction of Vitex negundo leaves
Any one of these may be used to purify Mica in preparation for Bhasma.
2. Another source states that it should be quenched 7 times in either Kanji or Cow Urine, then heated a further 7 times, quenching each time in Triphala Decoction, then heated another 7 times, this time quenching in Cow Milk.
