A 35 year old, marketing executive consulted me for his irritable bowel syndrome, suffering since five years. He presented his complaints obstinate constipation with mucus stool, which adheres with jelly like lumps sometimes. He had tenesmus and rumbling during and after stool. He had very offensive flatus which was very nuisance to his profession and runs to toilet, when passes it thinking that stool would come. He had itching and burning after passing flatus, worse at night. He also had haemorrhoids 10 years before, cured with some homoeopathic medication. He is fleshy with medium complexion, irritable when constipated, perspires more and exhausted even after little exertion or work. A similimum prescribed on this totality cured the patient with in three months

Can you guess the similimum, which has cured his complaint?
