Children with dark hair and eyes, delicate, sensitive, skin prone to intertrigo during dentition ( Lycopodium ), or convulsions with eruption of teeth ( Stannum ).

Disturbed functional activity of brain and spinal cord, from exhausting disease or severe mental shock, resulting in paralysis.

Causticum has Rawness or soreness: of scalp, throat, respiratory tract, rectum, anus, urethra, vagina, uterus (as if bruised, Arnica; as if sprained, Rhus ).

Melancholy mood: sad, hopeless; from care, grief, sorrow; with weeping, “the least thing makes the child cry.”

Intense sympathy for sufferings of others.

Causticum has Ailments: from long-lasting grief and sorrow ( Phosphorus ac. ); from loss of sleep, night watching ( Cocculus indicus, Ignatia ); from sudden emotions, fear, fright, joy ( Coffea, Gelsemium ); from anger or vexation; from suppressed eruptions.

Causticum Children are slow in learning to walk ( Calcarea phosphorica ).

Unsteady walking and easy falling of little children.

Constipation: frequent, ineffectual desire ( Nux ); stool passes better when person is standing; impeded by haemorrhoids; tough and shining, like grease; in children and nocturnal enuresis.

Causticum has Urine involuntary: when coughing, sneezing, blowing the nose ( Pulsatilla, [Squil.], Verbascum ).

Causticum Cough: with rawness and soreness in chest; with inability to expectorate, sputa must be swallowed ( Arnica, Kali carb. ); relieved by swallow of cold water; on expiration ( Aconite ); with pain in hips; remaining after pertussis; with expectoration chiefly at night.

Hoarseness with rawness, and aphonia < in the morning (< in the evening, Carbo vegetabilis, Phosphorus ).

At night, unable to get an easy position or lie still a moment ([Eup.], Rhus ).

Must move constantly, but motion does not relieve.

Cannot cover too warmly, but warmth does not >.

Faint-like sinking of strength; weakness and trembling.
