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-
1.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 also 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, in real life the flowers are placed in the jar containing clear water of stream and this is left in the sun. After a few hours, the extracts of flowers ooze out into the water.

2. 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.
