The invention discloses a plaster companion. The plaster companion is non-toxic volatile oil extracted from a 
plant. The 
plant belongs to the 
genus pinaceae. The non-toxic volatile oil is 
oleoresin exuded from the 
plant of the 
genus pinaceae pinus. A manufacturing method of the plaster companion comprises the steps that a, the part containing the volatile oil of the plant is smashed and distilledthrough introduced steam, and edible salt is added to distillate for 
salting-out separation and extraction to obtain the volatile oil; b, 
distillation under reduced pressure and refining 
fractional distillation are performed to collect the mixed distillate and 
turpentine of high, medium and low boiling ranges; the high boiling range is 125-140 DEG C / 10 mmHg, the medium boiling range is 85-125 DEGC / 10 mmHg, and the low boiling range is 45-85 DEG C / 10 mmHg; and c, 
absorbent cotton is used as a carrier to absorb the mixed distillate and the 
turpentine to be sub-packaged in aluminum-plastic composite bags, or the mixed distillate and the 
turpentine are sub-packaged in other containers such as plastic bottles and glass bottles. The plaster companion is a special 
scavenger designed for plasterresidue after a plaster is applied to an affected part of the 
skin, and an adopted material is a natural non-toxic and harmless liquid 
raw material and has a 
skin irritation function, and has an auxiliary 
treatment effect on 
muscle and 
joint pain. Therefore, the plaster companion is particularly suitable for the removal of the plaster residue. After cleaning by the plaster companion, the removal rate of the plaster residue reaches 100%.
