<s>[INST] Hi I have a health question. Friend of mine is landscaper/gardener and was weedwhacking some big weeds on a malibu, CA hill property when he later could not breathe, throat closing up, caughing. Doctors are saying it could be a weed form of euphorbia plant. It may have been inhaled into his form on hot CA afternoon. What can you tell me about chances of healing this? Lisa De Haven [/INST] Thanks for your question on Chat Doctor. In my opinion you should first consult pulmonologist and get done PFT (Pulmonary Function Test) and chest x-ray, CT THORAX. As possibility of allergic bronchitis and hypersensitivity pneumonitis (HSP) are high. Weeds can act as allergen and cause bronchitis attack. So PFT is needed to diagnose this. Long term exposure to weeds can cause HSP. It is interstitial inflammation caused by weeds. So CT THORAX is needed to diagnose this. And treatment of both are different.  So better to consult pulmonologist and diagnose him first. </s>
