Dorothy Shepherd, an English Doctor in post WWII London authored several books about Homeopathy, as she ran a clinic during and after WWII in London that exclusively used homeopathic medicines. She relates a story about Arnica that is quite incredible.

Back in those days, there were still milk carts, pulled by teams of horses and attended quite often by boys of between 12 and 15 years of age. The carts were very tall--generally the seat in which the milk boy sat would be anywhere from 10 to 15 feet off the ground. In this story, the cart was described as a large one.

A milk boy of about twelve fell from the top of the cart onto his head and onto the cobblestone street. He almost immediately went unconscious and was brought to Dorothy Shepherd's clinic. He was described as being cold, pale, swollen, bruised and had a very weak pulse. 

Dr. Shepherd gave him a dose of Arnica and in very short order he woke up, vomited, and laid back down and fell asleep (a very good sign when using homeopathy in acute illnesses or injury).  A couple hours later he woke up, asked for some food and got another dose of Arnica. A couple hours after that, he walked home and only missed a couple days of work.

Now, cobblestone streets are about as solid as you get. My guess is, without Arnica this young boy may have lost his life. This story illustrates why it is our go-to for head traumas, concussions, contusions and any sort of trauma that involves soft tissue.

But that is only the beginning of its uses. It is great as a surgery protocol, both before and after. Take it in a 200c potency the night before and on the morning of surgery and then again after the anesthetic wears off if there is pain. It will help prevent excessive swelling, bruising and also prevents infection!

It is excellent for hemorrhoids, varicose veins and is very connected to any sort of blood condition. If someone is having a stroke, it is much better even than baby aspirin for reducing the impact of the stroke.

It is an anti-hemorrhagic so if you give it on the way to the emergency room, you could very well stop a stroke in its tracks.

Arnica is also wonderful for pregnant moms who are sore from an active baby kicking her belly to the point of bruising. If it is taken during labor, is an excellent alternative to the vitamin K for the newborn, as the Arnica acts in a similar way, only without the potentially harmful side effects of vitamin K and is transmitted to the baby through the mother until the umbilical cord is cut.

Finally, though this is not at all an exhaustive list, I use it to prevent being sore when I wake up in the morning--an unfortunate symptom I guess of being nearly 50 years old. :)

I could literally go on and on about this amazing remedy! But, suffice it to say that Arnica is something you ought to look into. I would get it in the 200C (or CK) potency on Amazon or some other site. You won't regret it!.
