Everything I have found has charges. I don't have enough funds to pay the fee for it - I'm a student. I'm currently doing a research about the anthelmintic property of P.florida mushroom for my thesis.
There are many on these subjects, and I wish to advise you to select an appropriate journal for your invaluable work rather looking for a cheap, irresponsible, predatory journal. Publishing your invlauable work in predatory journals has no value at all,, and the credits you get through citations also will be in question. Kindly take not of it.
