A traditional remedy reported to control excessive fermentation and decrease gastrointestinal discomfort in horses, cattle and sheep. IAH Berg Oil is a combination of wood tars, turpentine oils and methylated spirits that has been used for many years and have been reported to decrease gas production associated with fermentation. Taken orally, BERG OIL does not irritate the mucous membranes of the mouth and the digestive tract. The actives in BERG OIL are reported to be calmative and may assist in relieving gastric discomfort. They may also help counteract the griping action of purgatives. Methylated spirits reduces the frequency of sudden muscle spasm, background spasticity with associated colic pain and functional disability caused by the excess gastrointestinal fermentation.
