Can RSO help with nausea and appetite loss?
Yes — many patients use RSO (Rick Simpson Oil), a concentrated full-spectrum cannabis oil taken by mouth, to calm nausea and bring back appetite, especially during chemotherapy and serious illness. THC, the main active compound in RSO, is well known for easing nausea and triggering hunger — the effect often called the munchies. A small dose before meals can make eating possible again.
The plate is in front of you and your body simply says no. Maybe nausea rolls through in waves; maybe food has lost all appeal; maybe the smell of dinner is enough to turn your stomach. When you can’t eat, everything gets harder — you lose weight, lose strength, and lose ground at exactly the moment you need to hold it. This is a plain-language look at how RSO helps with nausea and appetite loss, written for people who just want to keep food down again.
When eating becomes the hard part
Appetite loss and nausea travel together, and they have many causes. You might recognize one of these:
- Chemotherapy and radiation — among the most common causes of nausea, vomiting, and a complete loss of interest in food.
- The illness itself — cancer and other serious conditions can blunt appetite and change how food tastes and smells.
- Medications — many drugs, including strong painkillers, list nausea or appetite loss as a side effect.
- Cachexia (wasting) — a serious loss of weight and muscle that can come with advanced illness, where the body simply stops wanting fuel.
Whatever the cause, the result is the same exhausting bind: you need nourishment to keep your strength up, but the thought of eating makes you feel worse.
Why getting food back matters
Eating isn’t just comfort — during treatment it’s part of the treatment. Steady nutrition helps you keep weight on, hold onto muscle, tolerate therapy, and recover between rounds. When nausea and appetite loss drag on, weight falls, energy drains, and the whole road gets steeper. Easing those two symptoms can do more than help you feel better; it can help you stay strong enough to keep fighting.
What RSO is, briefly
RSO stands for Rick Simpson Oil — a thick, highly concentrated cannabis extract taken by mouth rather than smoked. It is full-spectrum, meaning it keeps the plant’s natural mix of THC, CBD, and other compounds, which many believe work better together than alone. Because it’s so concentrated, a meaningful dose can be as small as a grain of rice. If you want the full primer, read What is RSO? first.
How RSO eases nausea and brings back appetite
Cannabis has one of the longest track records of any natural remedy for these two symptoms — THC has been used for decades to settle the stomach and spark hunger. It works through the body’s endocannabinoid system, a network that helps regulate appetite, nausea, and digestion. Patients tend to describe two kinds of help:
- The nausea settles. THC acts on the body’s nausea and vomiting pathways, which is why it’s long been used to ease the queasiness that comes with chemotherapy.
- Hunger comes back. THC activates receptors that influence hunger signals and make food smell and taste more appealing — the familiar effect known as the “munchies.” For someone who hasn’t wanted to eat in days, that nudge can be the difference between an empty plate and a real meal.
Together, those effects can break the cycle: less nausea makes eating thinkable, and returning appetite makes it happen.
How to take RSO for nausea & appetite
The golden rule is start low and go slow. RSO is potent, and the goal here is to feel well enough to eat — not overwhelmed.
- Start small. Begin with a dose about the size of a grain of rice (roughly 10 mg).
- Time it around meals. Many patients take a small dose 30 to 60 minutes before eating to ease nausea and spark appetite, with a slightly larger dose at night.
- Increase slowly. Raise the amount gradually over days as your body adjusts, until nausea eases and food appeals again.
- Pair it with gentle habits. Small, frequent meals, bland easy-to-eat foods, and steady hydration all help RSO do its job.

A note for cancer and chemo patients
If you’re going through chemotherapy or radiation, cannabis can be a genuine help with nausea and appetite — but it belongs in your care plan, not around it. Your oncology team may already have prescribed anti-nausea medications, and RSO is meant to work with those, not replace them. Tell your doctor what you’re taking and when, so they can keep everything safe and pulling in the same direction. We’re building a fuller guide to using RSO during cancer treatment; in the meantime, the safest path is an open conversation with your care team.
Is RSO legal — and can I afford it?
In New Mexico, yes: cannabis is legal for adults 21 and over and for registered medical patients, and RSO is available through licensed channels. For many people in treatment, the real barrier isn’t the law — it’s cost, on top of everything else medical bills are already taking. Quality RSO can be expensive, and making it at home is dangerous. That gap is exactly why 2nd Star exists.

How do I get my appetite back during chemo?
Eating small, frequent meals, staying hydrated, and managing nausea all help. Many patients also use cannabis: a small dose of RSO taken before meals can ease nausea and stimulate appetite. Tell your oncology team what you’re using so it fits safely alongside any anti-nausea medications they’ve prescribed.
Does RSO help with chemo nausea?
Many patients find it does. THC, the main compound in RSO, has long been used to reduce nausea and vomiting from chemotherapy. RSO is used for symptom relief and works best alongside — not instead of — the anti-nausea medications your care team prescribes.
How does cannabis stimulate appetite?
THC activates CB1 receptors in the body’s endocannabinoid system, which influence hunger signals and make food smell and taste more appealing. This is why cannabis is widely associated with increased appetite, the effect commonly called the munchies.

Start with a dose about the size of a grain of rice, roughly 10 mg, taken by mouth. Many patients take a small dose 30 to 60 minutes before meals to ease nausea and spark appetite, and a slightly larger dose at night. Start low and increase slowly.
