Ginseng and Caffeine: What Happens If You Take Both
Updated 2026-09-20 · 5 min read
Plenty of people stir a honey sachet into their morning coffee. It is worth knowing what that combination does, because a brand that will not tell you is not worth trusting on anything else.
Ginseng is not caffeine
Panax ginseng contains no caffeine and is not a stimulant in the way coffee is. It is usually described as an adaptogen, a loose term for plants studied for effects on how the body handles stress. Whatever it does, it does not work like a shot of espresso.
ONYX contains no caffeine at all. If you take a sachet with coffee, all the caffeine in the equation comes from the coffee.
What the combination can do
The documented concern is that combining Panax ginseng with caffeine may compound stimulation of the central nervous system. Reported effects of that combination include jitteriness, a raised heart rate and elevated blood pressure. Both ginseng and caffeine have independently been associated with raised blood pressure in some people.
For most healthy adults having one coffee and one sachet, this is unlikely to be dramatic. It matters more if you already drink a lot of caffeine, if you are sensitive to it, or if you have high blood pressure.
Practical guidance
- If you are new to ginseng, space them out rather than taking them together, so you can tell what is doing what.
- If you already drink several coffees a day, consider a sachet on its own rather than stacked on top.
- Take it earlier in the day if you are sensitive. Ginseng has been associated with trouble sleeping in some people.
- If you feel jittery, that combination is the first thing to change.
The caffeine arithmetic
US health authorities generally cite around 400mg of caffeine a day as an upper limit for most healthy adults. A brewed coffee is roughly 95 to 165mg and many energy drinks run from 80mg to over 200mg per can.
Because a honey sachet adds none, swapping an afternoon energy drink for one is a way to reduce total caffeine rather than add to it. That is the genuine case for it, and it is a smaller claim than the category usually makes.
The other ginseng interactions
Caffeine is not the only thing Panax ginseng may interact with. Documented concerns include blood thinners such as warfarin, diabetes medication because ginseng can affect blood sugar, and some antidepressants including MAOIs.
If you take any prescription medication, ask a pharmacist. They will answer this specific question for free and they are good at it.
ONYX contains 300mg of Panax ginseng root extract per two-sachet serving, and no caffeine.

Can I put a honey sachet in my coffee?
Yes, and many people do. Be aware that Panax ginseng combined with caffeine may compound central nervous system stimulation, with jitteriness, raised heart rate and elevated blood pressure reported. If you are new to ginseng or drink a lot of caffeine, try them separately first.
Does ginseng have caffeine in it?
No. Panax ginseng contains no caffeine and is not a stimulant in the way coffee is. ONYX contains no caffeine from any source.
Will ginseng keep me awake at night?
It can in some people. Trouble sleeping is among the more commonly reported effects of Panax ginseng, particularly at higher intakes. If you are sensitive, take it earlier in the day.
Is it safe to take ginseng with an energy drink?
For most healthy adults an occasional combination is unlikely to cause problems, but it stacks ginseng on top of a substantial caffeine dose, which is the combination most associated with jitteriness and raised blood pressure. If you have high blood pressure or a heart condition, ask a doctor first.
