Calcarea ovi testae
Calcium carbonate (eggshell) · Mineral
Calcarea Ovi Testae shares the general properties of Calcarea Carbonica but has been little used clinically. It is selected for bland leucorrhoea and suggested for warts based on the traditional observation that egg-boiling water may cause warts on contact with skin. The keynote backache as if broken in two distinguishes it.
Key symptoms
- Simple, bland leucorrhoea
- Warts
- Backache as if broken in two (keynote)

Egg-shell. Trituration of the shell, not including its lining membrane.
Clinical
Leucorrhœa. Warts.
Characteristics
This preparation of Calcarea has been used in preference to others in cases of simple bland leucorrhœa. Water in which eggs have been boiled is popularly supposed to have the property of causing warts if brought in contact with the hands. This suggests Calc. ov. test. as possibly the best Calcarea preparation to prescribe in cases of warts. No doubt Calc. ov. test. has the general properties of Calc. carb. ostrear. (i.e., ordinary Calc. carb.), but it has been little used clinically, "Backache, as if broken in two," is a keynote.
