Fine and potent jows can be made without the inclusion of any bone.
Tiger bone is something that is highly unlikely you will get your hands on.
Many dit dar medicines are made strictly with herbs. Bone is not an herb. Herbs are plant material.
Sometimes insects are used in some types of jows, but for the bruise liniments that are required by the martial artist, there is not a need for jows that contain anything more than actual herbs.
As for the plastic question. The Harbin pharmacy started releasing tinctures and liniments in the last couple of years and with these new bottles they printed explanations of what it was and invited the opinions and comments of those who used these medicines.
Plastics are not what they used to be and there are many high quality plastics that are used in the packaging of liniments and other volatile liquids that do not leach. Clear and hard plastics are of this quality, whil the plastics that are thin and milky at the seams will likely be leeching to the substance it contains.
Still, if you are totally unsure, go for the glass bottle. :)
Dit Da Jow that one would use as a bruise liniment is readily available. Other stronger types that are used in bone setting and for more serious injuries are usually prescribed or given to you by your sifu.
Anyway, pain relief and relief of blood stasis are the main characteristics of a good dit da jow. Bruises will heal in a half to a quarter of the time they usually would and there is no residue scar tissue from the initial hematoma. THis is partly from the massage and partly from using the medicine. The massage breaks up the underlying scar tissue and the dit da jow keeps the blood flowing through the wounded tissue to prohibit a build up of cells that in turn will cause a scar that will effect the pliability of the affected area later in life.
