In south India, at the southern tip of the सह्य ranges, a mountain reputed for medicinal herbs, may still be seen. This mountain is known by the name " मरुत्वामल ". A legend connected with the origin of this mountain, is given in उत्तर रामायण , as follows:--

It was the time of the battle between श्रीराम and रावण . रावण 's younger brother विभीषण joined the side of राम and fought against रावण . The enraged रावण shot his arrow at विभीषण . In his endeavour to save विभीषण , लक्ष्मण fell down unconscious. राम and his followers discussed how लक्ष्मण could be revived. जाम्बवान् observed that there was a herb called "Droṇam" in one of the peaks of the हिमालय s and if it was brought at once, लक्ष्मण could be restored to his senses. हनूमान् flew to the हिमालय s immediately. But although he combed the forests there, he was not able to find the herb Droṇam. So he tore away and lifted a whole peak which was full of all kinds of medicinal herbs and returned to लङ्का . जाम्बवान् took the needed herbs from it and deposited the peak at the southern end of India. This is the present मरुत्वामल . (Mala means mountain).
