Tinctura Buchu. Tincture of Buchu. (B. P.) 

 Dose. — Twice that of the fluid extract. 



ACTION AND USES. 



The volatile oil and bitter principle act upon the diges- 

 tive organs as an aromatic bitter, promoting Appetite and 

 digestion in small doses, while large doses cause nausea and 

 vomiting in dogs. The volatile oil is absorbed and elimin- 

 ated by the mucous membranes, particularly of the bronchial 

 tubes and genito- urinary tract. It thus stimul.ites and dis- 

 infects the mucous membranes, slightly increases the secre- 

 tion of urine, and imparts its peculiar odor to the latter. 



The drug is of considerable value in the treatment of 

 chronic or subacute pyelitis, cystitis and urethritis. It is 

 stimulating, but only slightly irritating. Buchu has been 

 recommended in chronic nephritis, and is useful in irritation 

 of the urinary bladder, with frequent micturition, combined 

 with spirit of nitrous ether. Buchu is occasionally pre- 

 scribed in the later stages of bronchitis or in the chronic 

 form of this disease, and is employed in its native country 

 as a remedy for chronic diarrhoea and dysentery.
