There are quite a big list of natural products with antiviral properties. I did see quite a few mentions of antiviral activity while investigating antimicrobial activities while looking through many research papers on essential oils. I have found only a few mentions of epstein barr specifically. It always seems the way, when you are looking for something specific you cannot find it.
Herbal AntiVirals by Stephen Harrod Buhner is a good book which might be worth a look if you have not already. I have his Herbal Antibiotic book which is pretty good and it has served to make me aware of more recent things to research to combat the infection which causes CFS/ME/Fibro. Mine is extremely resistant and even eliminating it's biofilm and all the resistance that brings was not sufficient to help beat it. It did not make it any more susceptible to the antimicrobials that I used. It might not even be bacteria.
Anyway, back on topic. Here are the things that I was able to find. A combination of multiple things should be helpful, particularly helping restore more normal immune system function. Doing that without affecting the autoimmunity in ME caused by Increased Digestive Permeability and nervous system changes will be a challenge.

Reduced Colloidal Silver NOT Ionic silver - There is a lot of misinformation about Silver. The very few people who have had problems with it consumed massive amounts of IONIC silver mixed with Sodium Chloride to speed up the production process. Not using Distilled water could also of been a factor too. It might not even be Silver itself which is what destroys virus/micro-organisms. Other metals such as copper can have similar properties. The problem is finding very pure copper, I will have to look into that further.
For anyone who is still wary of using silver, despite it's value at defeating pathogens and Reduced Silver has defeated a biofilm/pathogen which healed a part of my digestive system, I suggest that you read the following webpage:
https://www.wgpeters.com/?page_id=932
Articles on Colloidal Silver and how tos on making it including Reducing Ionic Silver to metallic particles.
https://www.cgcsforum.com/index.php?topic=1143.0
The following page shows how to make a current regulating device for making Ionic Silver. Ionic silver can be converted to none charged silver particles by by raising the pH and using a reducing agent. That is what I do. A simpler alternative is to use a current regulating diode. A stirring device is also needed, there are guides on making a magnetic stirrer using a PC fan on youtube. A method of current switching would also be helpful but that can be done in a less technical manner by a switch or even by manually switching the contacts. I did outline a circuit to do that with a simple timer and relay but lost it before I made it when I lost 3 hard drives in the space of a week. There is another design which is more complete with current switching but I dislike the design due to it having a relatively high current, around 10mA, 1 to 3mA is best depending upon the water volume and low voltage ie 12V rather than the 38V that I use ATM. The voltage has to decrease as the resistance of the water decreases in order to maintain the current at a low level. If starting with 12V that gives very little room for reduction which is less than ideal.

Here is the 12V version. It might be too complicated for most people to build, a current regulating diode is the easiest option IMO:

Direct Link to the Silver Calculation spreadsheet, finding the link on the page can be difficult.

I have attached my updated spreadsheet which has a much longer timeline (excessive), this can be opened with Libreoffice, Openoffice or probably that microsoft version.

Immune system affecting supplements (On top of Vitamin C):
Probiotics, the good bacteria found in yogurt and other fermented foods, stimulate production of a component of the immune system which, in turn, stimulates natural killer cell activity, according to Edward R. Farnworth, editor of the "Handbook of Fermented Functional Foods."
Astragalus (Huang Qi) - immune system stimulant raising CD4 and lowering CD8 and increasing CD4/CD8 ratio and tends to normalise immune system markers. It is often used for fatigue and has shown benefit along with red sage (Dan Shen) herb in CFS/ME. It increases phagocytosis 4x greater than Echinacea. It is contraindicated in late stage Lyme disease as it can increase autoimmune response. This might be an issue with CFS/ME but seeing as it is used for CFS/ME it might be less of a problem.

Vitamin C, about a 1000 mg a day, has been found to boost NK cells
Glutathione, an essential antioxidant found in all cells, optimizes killing power of NK cells. Glutathione levels are depressed in states of chronic illness. Supplementing with glutathione may help normalize glutathione levels. In addition, vitamin C, vitamin E, N-acetyl cysteine (NAC), and alpha lipoic acid promote normal levels of glutathione.

beta-glucans -
https://www.wellmune.com/ - there are many different types of beta glucans and consuming a mixture might be helpful.
There are some other things, some tried on this forum before but some of it can be toxic. I will not repeat that here. However I must stress that I have not checked for any toxicity in the things I have listed. Some are known to be safe but the rest I cannot guarantee.
If I find any other antiviral essential oils while I am looking at antimicrobial eo I will post them. I do still have a lot to look at. Quorum Sensing Inhibitors are sorted, it's just Efflux Pump Inhibitors and Antimicrobials, the former being the most difficult, which I need to work out.
I would urge anyone to check all of this thoroughly before purchasing or using any of this to make sure it is suitable ie any side effects or possible toxicity.
