[MAIPC] [EXTERNAL] Re: Basal oil on ailanthus as stump treatment

Fri Aug 11 13:07:02 PDT 2023

I would just emphasize the importance of treating an *extremely* fresh cut.
And I have a feeling for whatever it's worth that a water-based rather than
oil-based treatment will be better for cut stump.

One other thing, just a reminder that there was the incident a few years
ago where someone suffered cardiac symptoms after cutting Ailanthus. See
for example:

https://www.health.harvard.edu/newsletter_article/Heart_Beat_Tree_of_heaven_may_be_hard_on_the_heart

So it may be wise to take extra precautions to avoid exposure!  Best and
cheers,   Steve
