A colleague hands you a small brown bottle at 4pm on a Tuesday and says it helped her shoulder. You read the ingredient list twice, put it in your bag, and still have no real idea what it is meant to do once it is inside you.
Hemp works through the endocannabinoid system, a signalling network of receptors, fatty messenger molecules and enzymes found throughout the human body. Cannabinoids from the hemp plant interact with that network, which helps regulate pain perception, sleep, appetite, mood and immune response. Hemp seeds are a food and carry almost no cannabinoids.
This is newer science than most people assume. Lisa Matsuda's team at the National Institutes of Health cloned the first cannabinoid receptor in 1990, publishing in Nature; Sean Munro's team cloned the second in 1993.
This article is educational and is not medical advice. Hemp foods and Ayurvedic preparations are not a substitute for diagnosis or treatment by a registered medical practitioner.
What is the endocannabinoid system?
The endocannabinoid system is a signalling network with three components: receptors called CB1 and CB2, fatty molecules the body makes called endocannabinoids, and enzymes that break those molecules down after use. CB1 sits mostly on nerve cells. CB2 sits mostly on immune cells and peripheral tissue.
Think of a thermostat rather than a switch. When something pushes the body off balance, cells build endocannabinoids on demand at the exact spot they are needed, and enzymes clear them within minutes.
The two best-studied of these molecules were found in quick succession. William Devane and Raphael Mechoulam's team at Hebrew University isolated the first one in 1992 and named it anandamide, after ananda, the Sanskrit word for bliss. The second, 2-arachidonoylglycerol, followed in 1995.
Cannabis has been recorded in Indian medical literature as Vijaya for centuries, and the researchers who found the body's own version reached for Sanskrit too.
How many cannabinoids does the hemp plant actually contain?
Cannabis sativa produces more than 150 identified cannabinoids, according to a 2020 review in iScience. THC and CBD are the two most abundant. The remaining compounds, including CBG, CBC and CBN, together make up less than 1% of the dry weight of the plant and are studied far less.
The more useful question is where in the plant those compounds sit. Cannabinoids are made in trichomes, the sticky resin glands clustered on flowering tops and, in smaller amounts, on leaves. Stalks carry very little. Seeds carry almost none.
Does CBD work by binding to cannabinoid receptors?
Mostly, no. Cannabidiol has low binding affinity for the CB1 and CB2 receptor sites that THC activates. A 2008 paper by Roger Pertwee in the British Journal of Pharmacology and later receptor work show CBD acting instead as a negative allosteric modulator at CB1 and through TRPV1, 5-HT1A serotonin and GPR55 receptors.
This is the part almost every hemp article in India gets wrong. CBD is routinely described as binding to your cannabinoid receptors the way a key fits a lock. The pharmacology does not support that.
A negative allosteric modulator does something subtler. It attaches at a secondary site and changes how the receptor responds to whatever else arrives, which is one reason CBD dampens some effects of THC rather than adding to them.
CBD is also called non-psychoactive constantly. Non-intoxicating is the accurate word, because a compound acting on serotonin receptors is by definition affecting the central nervous system. What it does not do is produce a high.
So CBD has many identified targets and no single agreed mechanism. Anyone telling you exactly how it works is ahead of the literature.
Do hemp seeds and hemp protein act on the endocannabinoid system?
No. Hemp seeds contain negligible cannabinoids, so hemp hearts, hemp protein powder and cold-pressed hemp seed oil do not act on cannabinoid receptors. Any CBD detected in seed products is surface residue transferred from flowers and leaves during harvest, not a compound the seed produces.
Hemp seed oil and CBD oil sit in similar bottles, carry similar leaf imagery and get confused constantly. They are different products from different parts of the same plant.
The value of hemp seed is nutritional. Roughly 21% protein, a favourable omega-6 to omega-3 ratio, and edestin, a protein that digests unusually well. Stir three tablespoons of hemp hearts into curd rice or sprinkle them over poha and you have added real protein to a meal that is usually short of it.
What you have not done is influenced your cannabinoid receptors, and any brand suggesting otherwise on a food label is breaking FSSAI rules. Hampa Wellness hemp hearts and hemp protein bars sit in the nutrition category for that reason.
The upside is that shopping gets simpler. Read the ingredient line, not the front label.
How does the endocannabinoid system respond to a topical hemp preparation?
Human skin contains its own cannabinoid signalling. Ständer and colleagues, writing in the Journal of Dermatological Science in 2005, found CB1 and CB2 receptors on keratinocytes, cutaneous nerve fibre bundles, mast cells, hair follicles and sweat glands. A topical applied to skin therefore meets receptors locally rather than travelling through the bloodstream.
Local action is the whole point of a balm or roll-on. Very little of what you rub onto a shoulder reaches the bloodstream, which is why topicals are regulated more leniently than oral formulations in India.
Hampa Wellness Hemp Muscle Pain Relief Oil is a topical Ayurvedic preparation combining Vijaya full-spectrum leaf extract, hemp seed oil, ashwagandha, eucalyptus and camphor, for external application to ease everyday muscular discomfort and stiffness. Classical Ayurvedic texts including the Sharangadhara Samhita describe taila preparations with Vijaya for muscular and nerve-related complaints.
The rule of thumb with any topical is that friction and warmth matter as much as the formulation. Massage until it absorbs, rather than dabbing it on and pulling your kurta back over it.
Why does an oral hemp oil dose often seem to do nothing on an empty stomach?
Because most of it never reaches circulation. Emilio Perucca and Meir Bialer, writing in CNS Drugs in 2020, estimated the absolute oral bioavailability of CBD under fasting conditions at approximately 6%, rising roughly fourfold when taken alongside a high-fat meal. Timing changes the dose more than most label instructions do.
The standard advice, a few drops under the tongue first thing in the morning, is close to the worst timing available. An empty stomach at 6am gets you a fraction of what the label implies.
CBD is strongly fat-soluble and poorly water-soluble. Taken with fat, more of it is carried through the intestinal lymphatic route and escapes first-pass metabolism in the liver.
In practice, that means after a meal with ghee, coconut oil, curd or nuts in it. A South Indian breakfast does this without any effort. Dry toast and black coffee does not.
Product quality is the other variable. Marcel Bonn-Miller and colleagues tested 84 CBD products from 31 companies for a 2017 research letter in JAMA and found nearly 70% inaccurately labelled, with 43% containing more CBD than stated and 26% containing less. Around one in five contained detectable THC. That study was conducted in the United States, but it explains why a batch-matched certificate of analysis matters more than a brand's design language.
What supports your own endocannabinoid system day to day?
Your body produces endocannabinoids continuously without any plant input. Exercise, sleep, dietary fat quality and stress load all influence endocannabinoid tone. A 2015 study by Johannes Fuss and colleagues in PNAS showed that the runner's high depends on cannabinoid receptors rather than endorphins, which had been the accepted explanation for decades.
Sit with that one. Endorphins are too large to cross the blood-brain barrier easily, whereas anandamide crosses without difficulty, and blocking opioid receptors in mice did not remove the calming, pain-dulling effect of running. A 2021 human follow-up in Psychoneuroendocrinology with 63 participants on treadmills found the same pattern.
So the 6am crowd doing loops around Cubbon Park are not chasing endorphins. They are producing their own cannabinoids, for free, with better bioavailability than anything sold in a bottle.
Habits that support endocannabinoid signalling, in rough order of evidence:
- Moderate-intensity aerobic exercise, 30 to 45 minutes. Sustained and moderate beats short and brutal for raising circulating anandamide.
- Consistent sleep timing. Endocannabinoid signalling follows a circadian rhythm, and irregular sleep disrupts it.
- Omega-3 and omega-6 fats in a sensible ratio. Endocannabinoids are built from arachidonic acid, a fatty acid your diet supplies. Hemp hearts, flax, walnuts and fish all contribute.
- Reducing chronic stress load, which alters CB1 receptor density over time.
Is hemp legal in India, and which products are permitted?
Yes, within two separate frameworks. Section 2(iii) of the NDPS Act, 1985 defines cannabis as charas and ganja, the flowering and fruiting tops, and expressly excludes seeds and leaves when not accompanied by the tops. Hemp seed foods fall under FSSAI standards. Leaf extract preparations fall under AYUSH licensing.
The distinction that matters in India is anatomical, not chemical. Flowering tops and resin are controlled. Seeds and separated leaves are not.
- Hemp seed foods. FSSAI Gazette Notification F. No. Stds/SC/A-1.34/N-1, dated 15 November 2021, added Standard 2.16, permitting hemp seed, hemp seed oil and hemp seed flour to be sold as food. Total THC is capped at 5 mg/kg in food and CBD at 75 mg/kg. Labels may not carry CBD health claims, show any plant part other than the seed, or use the words cannabis or marijuana.
- Vijaya leaf extract preparations. Manufactured as proprietary Ayurvedic medicines under the Drugs and Cosmetics Act, 1940 and Ministry of AYUSH licensing. Topicals are generally sold over the counter, while oral formulations are meant for use on a registered practitioner's advice.
Advertising sits under a third framework. Under the Drugs and Magic Remedies (Objectionable Advertisements) Act, 1954, no product may be advertised as a cure for scheduled diseases, which is why compliant Indian hemp content stays within relief and comfort language rather than promising to treat arthritis, anxiety or insomnia.
Where is the evidence strong, and where is it thin?
Evidence quality varies sharply by claim. Purified CBD has regulatory approval for specific rare childhood epilepsy syndromes on the strength of randomised controlled trials. Most consumer wellness claims rest on animal studies, small open-label trials or laboratory work, which is a much weaker foundation than product marketing usually admits.
The strongest human data concerns pharmaceutical-grade CBD in epilepsy, at doses far above anything in a wellness product. Topical cannabinoid research for musculoskeletal discomfort is promising and mostly small-scale.
Sleep, mood and general recovery claims are where the gap widens. Plenty of people report benefit; controlled evidence is limited and often confounded by expectation effects, which run strong here.
Saying so is not a weakness. The underlying receptor science is solid and three decades deep, while the research on what a specific consumer product does to you is still developing.
Which Hampa Wellness products relate to hemp and which to hemp seed?
Hampa Wellness sells two distinct categories. Hemp seed foods, including hemp hearts and hemp protein bars, are nutritional products under FSSAI standards with negligible cannabinoid content. Topical Ayurvedic preparations, including Hemp Muscle Pain Relief Oil and Period Cramps Relief Roll-On, contain Vijaya full-spectrum leaf extract alongside hemp seed oil and classical herbs.
Knowing which category you are buying prevents disappointment. Hemp protein is protein, chosen for amino acid profile and digestibility, and it will not do anything for a stiff neck. The leaf-extract topical is the one applied to the area that aches, as a supportive measure alongside rest and movement. Neither replaces medical treatment.
What else do people ask about hemp and CBD?
Will hemp products make you high?
No. Hemp seed foods sold in India must contain no more than 5 mg/kg total THC under FSSAI Standard 2.16, and legally manufactured Vijaya leaf preparations are formulated to stay within permitted THC limits. CBD itself is non-intoxicating. Products made from flowering tops or resin remain prohibited under the NDPS Act.
Is hemp seed oil the same as CBD oil?
No, and the confusion is widespread. Hemp seed oil is cold-pressed from seeds and contains essentially no cannabinoids, making it a nutritional and cosmetic oil. CBD oil is extracted from leaves or flowers, where cannabinoids are concentrated in resin glands. Check the ingredient line rather than the front label.
Can you have a weak endocannabinoid system?
The idea, called clinical endocannabinoid deficiency, was proposed by Ethan Russo in 2004 as a possible explanation for migraine, fibromyalgia and irritable bowel syndrome. It remains a hypothesis. No validated clinical test measures endocannabinoid tone, and no diagnosis of deficiency currently exists in Indian or international practice.
Does hemp protein powder contain CBD?
No. Hemp protein is milled from hemp seeds, which do not produce cannabinoids. Trace amounts occasionally detected come from resin transferred onto seed coats during mechanical harvesting, and hulling removes most of that. Choose hemp protein for its amino acid profile and edestin content, not for any cannabinoid effect.
Do you need a prescription for hemp products in India?
It depends on the format. Hemp seed foods need no prescription and are sold openly under FSSAI licensing. Topical Ayurvedic preparations are generally available over the counter. Oral Vijaya extract formulations are intended for use on the advice of a registered Ayurvedic or medical practitioner.
How long does hemp take to work?
There is no reliable single answer, and precise timelines in marketing copy should be treated with suspicion. Topical preparations act locally where applied. Oral absorption is slow, variable and heavily affected by whether food is present. Individual response differs enough that published averages tell you little.
Is CBD safe to take with other medicines?
Consult a doctor first. CBD inhibits several cytochrome P450 liver enzymes that metabolise a large share of common medicines, including some blood thinners and anti-epileptics, which means it can alter their levels. This interaction is well documented and is a genuine reason for medical supervision.
Are hemp products suitable for children?
No, not without medical supervision. FSSAI Standard 2.16 prohibits hemp seed products in foods intended for infants up to 24 months, and Indian hemp foods are labelled for ages two and above. Any use of cannabinoid preparations in children should involve a registered practitioner.
What is the most useful thing to understand about the endocannabinoid system?
That the human body runs a cannabinoid signalling network of its own, discovered barely three decades ago, quietly managing pain, appetite and recovery long before anyone sold you a bottle.
Understanding the endocannabinoid system makes you a harder person to sell to, which is the point. You will know whether you are buying food or an Ayurvedic preparation, whether cannabinoids are actually present, and what a certificate of analysis is for.
