^tZ^i^}       The  Pharmacy  of  Oxy-pinene.  523 
The  pinene  vapor  is  produced  by  allowing  a  current  of  dry  air  to 
pass  over  the  surface  of  volatile  pinene.  The  ozone  is  made  by 
silent  electrical  discharges  in  purified  air.  In  order  to  avoid  the 
production  of  nitrates  and  gaseous  peroxides,  the  air  which  is  used 
in  generating  oxy-pinene  must  first  be  freed  from  moisture ;  this  also 
allows  a  higher  degree  of  saturation  with  the  volatile  pinene. 
Oxy-pinene  vapor  may  be  inhaled  mixed  with  the  air  of  a  room  or 
directly  from  the  generator  by  means  of  a  suitable  mask.  For  the 
treatment  of  superficial  lesions  on  the  surface  of  the  body  it  is  used 
by  allowing  it  to  flow  directly  upon  the  affected  surface. 
When  inhaled,  oxy-pinene  acts  as  a  stimulating  expectorant. 
When  applied  to  the  skin,  it  acts  as  an  antiseptic  stimulant. 
Summarizing : 
Oxy-pinene  is  an  ozonide  of  pinene,  a  chemical  compound  con- 
sisting of  one  or  two  molecules  of  ozone  (Os)  linked  to  one  molecule 
of  pinene  (C10H16),  the  active  and  chief  constituent  of  oil  of 
turpentine. 
It  is  produced  in  two  forms,  a  vapor  and  a  pale  yellow  liquid  of 
honey-like  consistency. 
On  contact  with  moisture  it  breaks  down  into  peroxide  of  hydro- 
gen, oxides,  aldehydes  and  ketones  of  pinene. 
Exposed  to  high  temperatures,  auto-oxidation  takes  place. 
It  is  useful  in  treatment  of  tubercular  affections,  wounds,  ulcers, 
diseases  of  the  mucous  membranes,  eczemas,  hemorrhoids,  etc. 
It  is  an  antiseptic,  expectorant,  stimulant,  and  oxidizing  agent. 
Mixed  with  diatomaceous  earth,  one  part  to  two  parts,  it  makes  a 
suitable  powder  for  dressing  ulcers,  old  wounds,  etc. 
Made  into  suppositories  with  stearate  from  cocoanut  oil,  about 
one  per  cent,  strength,  it  is  very  useful  in  treating  diseases  of  the 
membranes  when  a  stimulating,  mild  antiseptic  is  required. 
In  a  compound  ointment  combining  astringent  and  drying  prop- 
erties with  its  antiseptic  and  stimulating  effect  it  is  useful  in  eczemas 
and  in  certain  cases  of  hemorrhoids. 
The  vapor  may  be  inhaled  direct  from  a  generator  or  indirectly 
mixed  with  air. 
The  liquid  may  be  applied  to  wounds  in  its  strongest  form.
