Evaluation of activated charcoal as treatment for Yellow tulp (Moraea pallida) poisoning in cattle.

The efficacy of activated charcoal as a treatment for cattle (n = 57) poisoned by Yellow tulp (Moraea pallida) was investigated. Treatment with activated charcoal resulted in full recovery, irrespective of the degree of posterior paresis, provided that this clinical sign did not develop within the first 12 hours after initial exposure to Yellow tulp-infested grazing. For instance, despite treatment, 1 of 7 cattle succumbed after manifesting mild posterior paresis 6 to 8 h after initial exposure and 3 of 3 treated cattle died after developing severe posterior paresis within 6 to 12 h.
