A.The hydrocortisone mentioned is naturally derived from soy, but it’s still classed as a drug and you would need to obtain it through a veterinarian. Like any cortisone, it can be used for almost any inflammatory or allergy based condition and has fewer side effects than the synthetic varieties. Asthma would be covered in this category and I have used it successfully many times for this problem; I would, however, stop using it if it didn’t give a positive response. I also like using BHI’s Asthma, sometimes in combination with their Cough and/or Bronchitis remedies. I have also had fairly good success using Seven Forest’s herbal Pinellia formula.
