Medicinal plants are known to Indian traditional healers since time immemorial. The plants were collected, by and large, from the wild and were used in many preparations of wellness products. India is endowed with diverse group of medicinal plants accounting for more than 8000 species which are being used in more than 10,000 herbal products. Ninety percent of herbal industry’s requirement of raw materials is meted out from the natural ecosystem – forests – resulting in ruthless exploitation and destruction of its natural habitats (Mathivanan et al. 2016). As one of the measures to conserve the precious species, commercial cultivation began which inadvertently brought the problem of pests and diseases leading to crop loss of various magnitudes. This chapter will discuss on major pests and diseases of some important medicinal plants like noni (Morinda citrifolia L.), glory lily (Gloriosa superba), makoi (Solanum nigrum), medicinal coleus (Coleus forskohlii), senna (Cassia angustifolia) and ashwagandha (Withania somnifera). Medicinal plants being used in health-care system and chemical methods of management of pests and diseases are becoming obsolete. It is a must that non-chemical, eco-friendly safer methods of management are essential which are also being discussed in this chapter.
