Even though there are many diseases which come under vata vyadhi, the common signs which a physician may come across are the sthanik shotha and sthanik sandhi shoola. Both of these tend to hamper the day to day life of the patient. Elaborately described abhyantara chikitsa as well panchakarma chikitsa both have its own significance in vata vyadhi. Looking at today s busy life style of patients it is difficult for them to follow the bahya snehan which has important role in many of the vata vyadhi as a part of chikitsa and also to get the symptomatic relief. Nirgundi (vitex negundo) has been described in bhavprakash under guduchyadi varga. It is stated that, it has vedanasthapan, shothaghna and shulaghna gunas and thus it is used as a prime dravya in many of the vatashamak kalpas of abhyantara as well as bahya use, for local application generally Nirgundi sidhha taila is used [1]. The contents of Nirgundi taila are Nirgundi patra and Nirgundi patra swaras. Conversion from Nirgundi taila to the Nirgundi ointment is achieved by adding different bases other ingredients. This is the sincere effort to convert this traditional 1

Introduction Ointments are semisolid preparations for external application to the body. They should be of such composition that they soften, but not necessarily melt, when applied to the skin. They are used primarily as vehicles or the bases for the topical application of the medicinal substances. Ideally, an ointment base should be compatible with the skin, stable permanent, smooth, non- irritating, non-sensitizing, inert and readily able to release its incorporated medication. [3] Thus by taking the advantage of the above qualities of the ointment s bases we can convert the traditional formulation of taila into ointment. Thus the bioavailability of the drug is also increased even though the form of the medicine is changed. To convert traditional formulation of Nirgundi taila into Nirgundi ointment. Objectives Preparation of Nirgundi taila (oil). Analytical testing of Nirgundi Taila (oil). Conversion of Nirgundi taila into Nirgundi ointment.

Name of herb Rasa Guna Virya Vipak Karma Nirgundi Katu, Tikta, Kashay Ushna, Laghu Ushna Katu Shothaghna Vedanasthapana Vatahara Anulomana Methods The drugs required for the preparation of Nirgundi Taila were procured from Shiva Ayurvedic Pharmacy, Sion, Mumbai, Maharashtra. The drugs were authentified from the Department of Dravyaguna, Y.M.T. Ayurvedic Medical College, Kharghar, Navi Mumbai. Formulation of Nirgundi Taila (Oil) Taila sidhha: 1. SS vessel was taken. 2. Tila taila was taken as the base for taila nirmana and was poured in the vol. 800ml (Table no. 1). It was heated till phenashanti. 3. Kalka of Nirgundi patra 200 gm was added in it (Table no. 1). 4. Nirgundi patra swaras of vol. 3.2 lit was added in that mixture (Table no. 1). 5. The mixture was kept on low flame and continuous stirring was done till all the taila sidhha lakshanas were observed. 6. After achieving this end point the taila was filtered using the cloth. 7. The taila sample was subjected to Lab. testing. 4

The prepared Nirgundi taila was observed for the following sneha paka lakshanas. [2] Varti parikshan the kalka was turned into a soft mouldable mass, that it can be rolled over fingers to form a varti. Shabda parikshan When such a varti (mouldable mass of kalka dravya) is placed over fire, it does not produce cracking noise. The same taila (oil) was heated using water bath. The following bases Bee wax, soft paraffin, hard paraffin were added in the above said proportion (Table no. 3). The mixture was stirred continuously till all the base added is mixed completely, then addition of volatile substances were done in the above said quantity (Table no. 2). The ointment was filled in the container & labelling was done. Three batches were done for the evaluation. Diagram 3 Nirgundi taila ointment. Analysis of raw material Table no. 5.

The ointment readily spread on skin when applied on the skin topically and pushed gently. Discussion There were no objectionable changes in the laboratorial parameters even after converting the Nirgundi taila into Nirgundi ointment. The odour of both Nirguni taila and Nirgundi ointment was Karpoora Gandhi. The Sparsha of Nirgundi taila was Snigdha while of Nirgundi ointment was soft denoting its snigdhata. The ph of the Nirgundi ointment (avg. 4.54) remains nearly the same as that of the Nirgundi taila (avg. 4.06). The LOD value of the Nirgundi ointment which is suggestive of the moisture percentage is also minimum (avg ), thus there are least chances of microbial contamination. The medicinal content of the formulation is basically Nirgundi, which just made to disperse into a different therapeutic form the addition of volatile ingredients in it gives the counterirritant warm sensation to the Sandhi (joints) upon which it is applied, also the bio availability of the medicament in the formulation is not hampered because of this conversion. Nirgundi ointment is highly significant than Nirgundi taila by above said parameters in the management of vata vyadhi. Conclusion The traditional formulation of the Nirgundi taila has been successfully converted into Nirgundi ointment which can be used easily by the individuals. Even the physicochemical values are least deviated in the finale product. References: 1. Bhavpraksh; Bhavpraksh Nighantu part 1; Brahmashankar Mishra; Guduchyadi Varga - 8
