The Homoeopathic system of medicine was found and developed on the law of similars and other natural laws of healing. It is being practiced worldwide in about 80 countries. Homeopathy has gained immense popularity and has garnered much attention by virtue of its medicines being safe and non-toxic and free from side-effects.

The utility of arnica has been explored and proven by several research studies for its properties as;

There are plenty of studies to prove that this plant is loaded with plenty of health benefits. It is primarily used as a "trauma remedy" but the remedy has a lot more to offer than just management of bruises, contusions, and hematomas.

Since homeopathic medicines act on a deeper level, a similar effect can be seen when arnica is indicated. It is not only useful for the bruised body, but also for the bruised soul or a person who does not forget the pain.

How Fast Does Arnica Work?

One of the most frequently asked questions is how fast does arnica cream works or how fast does arnica medicine work?

The answer to this is - It entirely depends upon every individual person's bodily reaction to the medicine. While some people may notice results within a few days of the use of medicines or the cream, others may get results even later.

This is the sole basis of the homeopathic system of medicine - Which is that it works on individuality if a certain medicine suits the person and if it is prescribed in an accurate potency and dose, the results will be visible sooner.

Also, in long-standing cases where pathological changes have taken places such as osteoarthritis, rheumatoid arthritis, and chronic heart diseases, the medicine will simply relieve symptoms as such disease processes are irreversible.


Arnica is the best-known homeopathic medicine that is available to the general population in the form of liquid medicines in various potencies, tinctures, ointments, lotions, hair oil, shampoo, and creams.

Although homeopathic medicines do not require any specific prescription and can be purchased easily from homeopathic pharmacies, it is always a safer option to consult a qualified homeopathic physician to get a tailor-made dosage. Arnica can also be used safely with other medications
