INTRODUCTION
ADHD is a neurobehavioral condition affecting both children and adults characterized by Attention deficit, motor overactivity and motor restlessness and impulsivity. In Ayurveda it is often correlated with Unmada, a condition of the manovaha srotas. Mahapaisachika Ghrita has been mentioned in Caraka Samhita Chikitsasthana Adhyaya 9 Sloka 45-48 (Cakrapanidatta, 2008) with its use in conditions like Unmada, Apasmara and Graha rogas among others. It has also been mentioned in Sahasrayoga Ghrita prakarana 44 (Nishteshwar, 2008).
It contains a total of 23 drugs processed in Go Ghrita. Those are Jatamansi, Haritaki, Shankhapushpi, Charati, Kapikacchu, Vacha, Trayamana, Agnimantha, Kshriakakoli, Coraka, Katurohini, Vayastha, Varahi, Shatapushpa, Mishreya, Guggulu, Shatavari, Amalaki, Rasna, Gandha Nakuli, Shyonaka, Shalaparni and Vruschikali. It has also been hailed as Buddhi and Smruti Karam as well as Anga Vardhana especially in children (Bala).
GC-MS is a potent analytical method employed to detect volatile and semi-volatile components in complex herbal formulations. It facilitates possible correlation between chemical compounds and pharmacological effects offering scientific basis for Ayurveda formulations.
In the present study, The GC-MS analysis of Mahapaisachika Ghrita revealed the presence of various compounds exhibiting neuropharmacological effects by modulating neurotransmitter systems, showing anti-oxidant and anti-inflammatory properties or govern neuronal signalling pathways which are significant in attention and executive function.
When ghrita is administered orally, gastric lipases start the digestion of the triglycerides into monoglycerides and eventually free fatty acid (Aeri and Tripathi, 2022). The embedded active constituents are dissolved and absorbed better due to ghrita being a lipid-based formulation thereby improving solubility (Jadhav and Tare, 2025). A solubilised solid solution containing microionized particles (Aeri and Tripathi, 2022). The lipid-based drug formulation is thus absorbed and distributed by altering the electrolyte-based transport systems, drug uptake, efflux and disposition (Jadhav and Tare, 2025).
Ghrita acts like a trojan horse. It transports the active therapeutic constituents beyond the blood brain barrier by one of three mechanisms such as lipid mediated diffusion, rapid carrier-or-receptor mediated transport or crossing the blood brain barrier as a complex to provide restorative and protective effects on the nervous tissue by cleansing the damage through its antioxidant and anti-inflammatory effects and enhancing prime neural signalling molecules (acetylcholine modulation) (Satapathy et al., n.d.).
Nasya karma facilitates a more targeted absorption of active components when compared with other modes of administration. When ghrita is the solvent administered through the nose, due to its characteristic as a lipophilic compound it is likely absorbed either by the olfactory pathway through the olfactory epithelium at the roof of the nasal cavity (Xinchen et al., 2023). It can then enter the olfactory Sensory neurons or it can diffuse through gaps between cells (Koo et al., 2024). The other pathway involved is the Trigeminal Pathway where the compounds are absorbed along its branches providing a direct path to deeper cerebral regions (Xinchen et al., 2023).

Gas Chromatography Mass Spectrometry
Gas Chromatography Mass Spectrometry is a technique used to identify and measure chemicals within a sample. Gas Chromatography separates the different chemicals present in a sample whereas Mass Spectrometry identifies and quantifies chemicals by measuring their weights (mass-to-charge ratios). The entire process includes sample introduction, separation by gas chromatography, detection by Mass Spectrometry and Data Detection.
Initially the provided sample is introduced by placing it in the instrument. If it is a liquid, it is aptly vaporized. Then the vaporised sample is pushed through a thin tube through which chemicals travel at different speeds based on their specific properties. As each chemical pass through the tube, they all enter the Mass Spectrometer. There they are broken into charged fragments which are then measured. These measurements result in the formation of a pattern which is unique for each chemical. Finally, a graph is produced which shows what chemicals are present and along with each of their quantities.

DISCUSSION
The blood brain barrier is selectively permeable to lipid soluble substances. Ghrita is a complex fat with herbal constituents which are lipid soluble. Hence, they diffuse directly through the blood brain barrier’s lipid layers and facilitate CNS access. This process is known as Lipid mediated free diffusion
This study identified the presence of antioxidant, anti-inflammatory and neuroprotective constituents in Mahapaisachika Ghrita which may help in reducing the severity of ADHD symptoms.
Oleic Acid
Oleic acid is necessary for the proper development and functioning of the brain. It is used to synthesize myelin phospholipids and acts as a neurotrophic factor by promoting axonal and dendritic growth, enhancing neuronal growth and aggregation alongside the facilitation of synapse formation.
PET imaging shows evidence of microglial activation in the dorsolateral prefrontal cortex and orbitofrontal cortex in adults with ADHD (Schnorr et al., 2024). Activated microglia release pro-inflammatory cytokines like IL-1β and TNF-α, glutamate and other mediators that can impair neuronal development, myelination and synaptic functioning (Anand et al., 2017). These potentially contribute to ADHD symptoms such as inattention and hyperactivity. Oleic acid is an endogenous agonist of Peroxisome-Activated Receptor Gamma (PPAR-γ) (Honda et al., 2025), a ligand-activated transcription factor belonging to the nuclear receptor superfamily. PPAR-γ agonists are broadly neuroprotective and anti-inflammatory, with the ability to inhibit microglial activation and downregulate pro-inflammatory cytokines such as IL-6 and TNF-α (Priya et al., 2024). Therefore, it addresses the neuroimmune dysregulation in ADHD pathophysiology by limiting neuroinflammation and improving oxidative resilience.
Docosahexaenoic Acid
DHA is the main omega-3 fatty acid in the brain and a principal component of neuronal membrane structure required in high concentrations for optimal neuronal functioning (Rodríguez et al., 2019). Supplementation with DHA has been shown to maintain and improve brain functioning by influencing membrane structure, fluidity, signalling pathways, receptor systems, enzyme activities and synaptic plasticity. Several observational studies have suggested that children with ADHD have an abnormal PUFA profile wherein reduced plasma concentrations of DHA and Eicosapentaenoic Acid (EPA) are seen along with lower erythrocyte total n-3 PUFA levels. Greater severity in ADHD symptoms has been linked with low blood levels of DHA and EPA (Chang et al., 2018).
DHA is the precursor of Docosanoids like Resolvins and Protectins (NPD1). Resolvins help promote the resolution of inflammatory processes by down-regulating NF-κB whereas NPD1 protects neuronal cells from oxidative-stress induced apoptosis (Bradbury, 2011). Reduction of DHA in the brain leads to reduction of both dopaminergic as well as serotonergic transmissions. N-3 PUFAs like DHA modulate neuronal signalling. DHA and its precursor EPA help balance immune functions by reducing membrane arachidonic acid and inhibiting PGE2 synthesis thereby reducing pro-inflammatory signalling. They also act as precursors for anti-inflammatory molecules and inhibit free radical generation and oxidative stress leading to an increase in anti-inflammatory action. DHA also helps in the regulation of several dysregulated biological systems like Hypothalamic-Pituitary-Adrenal Axis (HPA) stress response, Autonomic Nervous System activity and Gut Microbiota Axis (GBA) (Chang, 2021).
Beta Sitosterol Acetate
Beta Sitosterol acetate is an esterified derivative of the plant sterol Beta Sitosterol where the hydroxyl group is acetylated increasing the lipophilicity and potentially altering bioavailability. It becomes more fat soluble.
In ADHD models deficits have been found in visual-spatial working memory tasks as well as memory challenges tied to attentional control failures (Luo et al., 2019). It has also been found that there is reduced mitochondrial respiration, lower ATPase activity, depolarized membrane potential, along with elevated superoxide in frontal cortex-relevant cybrid models playing a part in bio-energetic deficits and impaired pre-frontal dopamine/serotonin signalling. These factors affect symptom severity (Verma et al., 2016).
Beta Sitosterol improves Spatial Learning and recognition memory by reducing Aβ plaques and BACE1 expression, indirectly addressing shared synaptic dysfunction (Verma et al., 2016). It has the ability to mitigate oxidative/nitrosative stress and enhance mitochondrial function in the Frontal Cortex (Vafaei et al., 2024).
Lauric Acid, Methyl Ester (Methyl Dodecanoate/Methyl Laurate)
Methyl Laurate is involved in the inhibition of EGR1 receptor. Early Growth Response 1 is an early gene and transcription factor that plays a key role in synaptic plasticity, neuronal activity, learning, memory, and response to stress and reward. These are the processes often disrupted in ADHD (Duclot and Kabbaj, 2017). EGR1 regulates neuronal plasticity through pathways involving NMDA receptors and Long-Term Potentiation (LTP) in brain regions such as the pre-frontal cortex, hippocampus, striatum, and amygdala, which are implicated in attention, executive function, and dopamine signalling relevant to ADHD (Bristot et al., 2024).
NF-κB is a transcription factor of prime importance in inflammation, oxidative stress, and immune responses. In ADHD, due to neuronal damage, neuro-inflammation and disrupted signalling in prefrontal and cerebellar cortices, it leads to an overactivation of the NF-κB factor (Zheng et al., 2025). Mast cell activation in ADHD may be a trigger for NF-κB via TLR8, MAPKs, and other mediators, leading to glial interactions, Blood-Brain Barrier breakdown, and HPA axis dysregulation (Song et al., 2020). Trans-fatty acids exacerbate ADHD through microbiota-gut-brain axis disruption which indirectly activates NF-κB-linked immune pathways during critical neurodevelopmental windows (He et al., 2025). An inflammatory ADHD biotype correlates with chronic stress and heightened NF-κB activity, promoting chemokine signalling and IL-17 pathways (Schnorr et al., 2024).
Methyl Laurate decreases the levels of lipopolysaccharide induced Nuclear Factor κ-B (NF-κB) in murine macrophages found in mice (Sivinski et al., 2020). They have functional similarities with human macrophages in processes like phagocytosis, production of TNF-α and IL-6 as well as the mechanisms of NF-κB pathway activation (Chen et al., 2023).
Octanoic Acid, Methyl Ester (Methyl Caprylate)
It is also known as Caprylic acid which is a medium-Chain (C8) Monocarboxylic Saturated Fatty Acid (MCFA) (PubChem, n.d.). It is a straight chain isomer of valproic acid (Altinoz et al., 2020) that provide an alternative energy source (ketone bodies) for neurons (Norgren et al., 2020), supporting mitochondrial function and synaptic activity, which is of particular relevance in conditions with impaired glucose metabolism, as seen in neurodevelopmental disorders like ADHD and Alzheimer’s disease (Chung et al., 2021). Under the conditions of low glucose availability, by the incomplete oxidation of fatty acids ketone bodies are produced which are metabolized by the brain to act as an alternative to glucose (Farah, 2014).
The small molecular size and high lipophilicity of caprylic acid facilitate its ready penetration across biological membranes, contributing to its high absorption and CNS delivery if administered intranasally as Nasya (Taléns-Visconti et al., 2023). Unlike Long-chain fatty acids, MCFAs can quickly cross the Blood-Brain Barrier, directly penetrate the mitochondrial matrix and have intramitochondrial conversion to Acyl-CoA thioesters and get directly processes by the brain (Fan et al., 2023).
Linalool and Related Terpenoids
When ingested linalool is metabolised in the gastro-intestinal system into geraniol, nerol and α-terpineol (Milanos et al., 2017). In rat models, geraniol is found to have sedative and hypnotic activity (A.L et al., 2018). It lowered the protein levels of neuro-inflammatory markers like IL-1β, iNOS, NF-κBp65 and COX-2 as well as down-regulated inflammatory genes like MCP-1, TNF-α, IL-6, IL-1β and IDO-1 (Eman and Abdulmalek, 2022). It was also seen to have reduced the concentration of oxidative damage indicators like malondialdehyde, nitric oxide and xanthine oxidase and boosted the activity of neuronal antioxidant enzymes (Eman and Abdulmalek, 2022). It increased levels of reduced glutathione, catalase, Glutathione-S-Transferase (GST) and Superoxide Dismutase activities (Eman and Abdulmalek, 2022). It also improved learning and memory in the same model (Eman and Abdulmalek, 2022).
Increased Acetylcholinesterase (AChE) activity leads to hippocampal inflammation ad impaired cholinergic status. Geraniol is found to suppress AChE, thereby improving cognitive abilities (Eman and Abdulmalek, 2022).
Nerol has been found to have neuroprotective, anti-oxidant, memory enhancing properties, especially in models related to neuro-degeneration (Ghashghaie et al., 2019).
CONCLUSION
The identification of compounds such as stearic acid, oleic acid among others through GC-MS analysis emphasizes the therapeutic potential of Mahapaisachika Ghrita in the management of ADHD symptoms through anti-inflammatory and anti-oxidant as well as neuroprotective pathways.
