A study of gamma-irradiated Indian medicinal plant products was carried out using electron paramagnetic resonance (EPR) spectroscopy. Improved approaches like high-power measurement, microwave saturation, and thermal behavior of the radicals were explored for detection of irradiation. Aswagandha (Withania somnifera), vairi (Salacia reticulata), amla (Emblica officinalis), haldi (Curcumin longa), and guduchi (Tinospora cordifolia) exhibited a weak singlet at g = 2.005 before irradiation. Aswagandha, immediately after radiation treatment, revealed a complex EPR spectrum characterized by EPR spectrum simulation technique as superposition of 3 paramagnetic centers. One group of signal with organic origin was carbohydrate and cellulose radical and the other was isotropic signal of inorganic origin (g⟂ =2.0044 and g|| = 1.9980). However, other products did not exhibit any radiation-specific signal after irradiation. Power saturation and thermal behavior techniques were not suitable for these products. However, amongst all the 3 approaches, high-power measurement of EPR spectra emerged as a suitable technique in identification of the irradiated aswagandha.

The confirmation of an immunomodulatory protein in guduchi stem showing lymphoproliferative and macrophage-activating properties reinforces the rationale of the use of guduchi preparations in several Ayurvedic medicines for immunomodulation. To our knowledge, this is the first report of an immunomodulatory protein isolated from guduchi.
Concept of Saviryta Avadhi (shelf-life) of Ayurvedic dosage forms is well-defined in classics of Ayurveda. Information on this is scattered in initial classics of Ayurveda like Charaka Samhita, but focused well after 13(th) Century AD in texts such as Vangasena Samhita, Sharangadhara Samhita and Yogaratnakara. Though the concepts have a strong background; considering the pharmaceutical development, a need is felt to re-evaluate the age old concepts by following current norms.
It is believed that the enhanced microbicidal and tumoricidal capability of activated macrophages is related to the remarkable increase in the production of oxygen metabolites. Both the production of H2O2 and the oxidation of NAD(P)H are directly dependent upon NAD(P)H-oxidase. It has been established that the respiratory burst is due to activation of NAD(P)H-oxidase localised in the plasmalemma. Myeloperoxidase is believed to be involved in augmenting the cytotoxic activity of H2O2. It was observed that the macrophage cell line J774A.1 when treated with Tinospora cordifolia (guduchi) and LPS showed enhanced NADH-oxidase, NADPH-oxidase and myeloperoxidase production as compared to macrophages treated with medium alone. The direct drug treatment to J774A cells showed activation as assessed by biochemical assays. These results suggest that high NADH-oxidase, NADPH-oxidase and myeloperoxidase activities may account for tumoricidal and microbicidal properties via macrophage activation.
