_Headaches_ generally must be treated with reference to their cause. _If from Constipation_, Castor Oil (83), Kaladana (187), Myrobalans (256), or other purgatives. _Of Fever_, hot water stupes to the nape of the neck (393). _From Bilious derangement_, the same purgatives preceded by a dose of Calomel (three grains) if at hand, and followed by Sal Ammoniac (328*). _Nervous, Hysterical, and Rheumatic Headaches_ often yield to Sal Ammoniac (328), persevered in for a few days, and the local use of Camphor Lotion (71*). _From suppression of the Menstrual_ _Discharge_, Leeches to the inner surface of the thighs (210). _From stoppage of bleeding from Piles_, Leeches to the verge of the anus (210); in both these last cases Aloes (19) should be given internally. The other measures occasionally useful are Ginger Plaster (157), Hot Water Fomentations (393), and Mustard Poultices or Mustard Foot-baths (248) to the extremities. _Heart, Palpitations of._ See _Palpitations_. _Heartburn_ often yields to Lime Water (221) given with milk or with Omum Water (317); or with Chiretta (98), if associated with indigestion. _Hepatitis._ See _Liver, Inflammation of_. _Hoarseness_ may be treated by inhalations of the vapour of Hot Vinegar (377*), or Decoction of Abelmoschus (3), by gargles containing Capsicum (78*), Black Pepper (300), or Moringa root (238); by chewing Ginger (158), or allowing a piece of Catechu (89) to dissolve in the mouth. _Hooping Cough._ In the early stages regulate the bowels with Castor Oil (83), and give Country Ipecacuanha (370) and Sal Ammoniac (329). As soon as the feverish symptoms have subsided give Alum (28*); should this fail, try Sulphate of Iron (180), with or without Asafœtida (37). If weakness and emaciation exist, or in very obstinate cases, give Fish Liver Oil (140); Mustard Poultices (252) and friction with Opium Liniment (291) to the spine seem useful in the chronic stage. _Hydrocephalus_ (_Water on the Brain_) occurring in weak, emaciated children of a scrofulous habit occasionally improves under Fish Liver Oil (139). _Hysterical Affections._ Amongst the means useful in controlling these are Asafœtida (35*), Aloes and Asafœtida Pills (19), Jatamansi (184), Omum Water (318), Turpentine Enemas (364), and Cold Water Affusion (386). _Indigestion, or Dyspepsia._ Tonics, as Chiretta (98, 99*), Sweet Flag Root (12), Country Sarsaparilla (163), and Guluncha (352), combined with stomachics, as Cloves (105), or Cinnamon (102), Capsicum (79), and Omum Water (318*), offer the best prospect of success. _With great increased Secretion_, Butea Gum (62). _With acidity of the Stomach_, Lime Water (221). _With torpidity of the Bowels_, Tincture of Kariyát (192), Without strict attention to diet, and careful regulation of the bowels and other secretions, medicines will have comparatively little effect.
