What is 'Coli basil'? Is one kind of basil plant you are talking about?

If so, you can just clone and express the gene in that basil, as the way described in 'Molecular pharming'. Many people have tried to produce 'recombinant proteins' in plants (ex. tobacco). However, the most tricky part of it is their 'post-translational modification' for the protein. In plants, they have different pathway in doing post-translational modification than in human. So, the produced 'proteins' may not suitable for human use without a fix. 

By the way, human epidermal growth factor has already been expressed in transgenic plants-- transgenic potato. See attached paper.
