The time-tested Ayurvedic medicinal food, Chyawanprash, has been a part of the Indian diet since ancient times. It is an extremely concentrated mixture of extracts from medicinal herbs and processed minerals, known for its immunity boosting, rejuvenating, and anti-oxidative effects. In this study, we have evaluated the anti-inflammatory potential of Patanjali Special Chyawanprash (PSCP) using the zebrafish model of inflammation. Zebrafish were fed on PSCP-infused pellets at stipulated doses for 13 days before inducing inflammation through lipopolysaccharide (LPS) injection. The test subjects were monitored for inflammatory pathologies like behavioral fever, hyperventilation, skin hemorrhage, locomotory agility, and morphological anomaly. PSCP exerted a strong prophylactic effect on the zebrafish that efficiently protected them from inflammatory manifestations at a human equivalent dose. Expression levels of pro-inflammatory cytokines, like interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), and interleukin-1 beta (IL-1β), were also reduced in the LPS-stimulated zebrafish fed on PSCP-infused pellets. Skin hemorrhage, hyperventilation, and loss of caudal fins are characteristics of LPS-induced inflammation in zebrafish. PSCP prophylactically ameliorated skin hemorrhage, restored normal respiration, and prevented loss of caudal fin in inflamed zebrafish. Under in vitro conditions, PSCP reduced IL-6 and TNF-α secretion by THP-1 macrophages in a dose-dependent manner by targeting NF-κB signaling, as evident from the secreted embryonic alkaline phosphatase (SEAP) reporter assay. These medicinal benefits of PSCP can be attributed to its constitutional bioactive components. Taken together, these observations provide in vivo validation of the anti-inflammatory property and in vitro insight into the mode-of-action of Chyawanprash, a traditionally described medicinal food.

The widely used cancer treatment, chemotherapy, causes severe long-term neuropathic pain in 30–40% cases, the condition clinically known as chemotherapy-induced peripheral neuropathy (CIPN). Approved conventional analgesics are sometimes ineffective, while others like opioids have undesirable side effects like addiction, seizures, and respiratory malfunctioning. Tricyclic antidepressants and anticonvulsants, although exhibit anti-allodynic effects in neuropathy, also have unpleasant side effects. Thus, alternative medicines are being explored for CIPN treatment. Despite scattered reports on different extracts from different plants having potential anti-allodynic effects against CIPN, no established medicine or formulation of herbal origin exists. In this study, efficacy of an herbal decoction, formulated based on ancient medicinal principles and protocols for treating neuropathic pain, Divya-Peedantak-Kwath (DPK), has been evaluated in a paclitaxel (PTX)-induced peripheral neuropathic mouse model. We observed that DPK has prominent anti-allodynic and anti-hyperalgesic effects and acts as a nociceptive modulator for CIPN. With exhibited antioxidative effects, DPK restored the redox potential of the sciatic nerves to the normal. On histopathological evaluation, DPK prevented the PTX-induced lesions in the sciatic nerve, in a dose-dependent manner. It also prevented inflammation by modulating the levels of pro-inflammatory cytokines involved in CIPN pathogenesis. Our observations evinced that DPK can alleviate CIPN by attenuating oxidative stress and concomitant neuroinflammation through immune modulation.
