Inula falconeri, Inula koelzii, Lactuca dissecta and Anthemis nobilis were collected from Himalaya and Hindukush ranges of Pakistan and their allelopathic effect was studied through Sandwich and Homogenated Sandwich methods. The study also aimed at analyzing whether method and concentration can affect the overall results.  The results showed that method has no significant value; however, concentration of leaf leachates has highly significant value for exploring the inhibition or stimulation pattern of the plant species.

Key words: Allelopathy, Sandwich and Homogenated Sandwich methods, medicinal plants of Pakistan.
