There are two methods of preparing flower remedies viz. the Sun method and the boiling method. Although discovered by Dr. Bach, these two methods are still followed for extracting the flower essence. The two methods are collectively called as `potentization`. The basic difference of flower remedies with homeopathy lies in the preparative method of flower remedies.

The two types of methods in flower remedies are

Sun Method: Dr. Bach found that the curative properties of plants are localized in the flower heads. He expanded the principle and was sure that the dew that is accumulated on the flowers also possesses some of the curative properties. In order to prove himself right he collected the dew that actually was deposited over the flowers and tested them. Dr. Bach discovered that the essence of the flowers is also present in the dewdrops but the flower essence is more potent in the dewdrops that are exposed to sun.

Practically, it is not possible to collect so many dewdrops so this sun method came into the picture. Sun method requires equipments like a clean crystal bowl, purified water, amber glass bottle, funnel and brandy. For this method, the flowers have to be picked up in full sunshine. The flowers are placed in the jar containing clear water of stream and this is left in the sun. One has to make sure that no shadow interrupts the clear sunlight so the place is very important. After a few hours, the extracts of flowers ooze out into the water. As per Dr. Edward Bach, the sun transfers the healing power of the flowers into the medium of the water, which becomes energetically impregnated. The derived remedy can be stored in a stock bottle. For treating ailment, the remedy has to be diluted with water.

Boiling Method: Boiling method is almost as same as sun method. Here the flower is placed in the jar containing clear water of the stream and then it is boiled. The flower extract pass out in the water. But there is one restriction in the boiling method. It cannot be used for the flowers that are heat sensitive.
