That's fine but grapefruit reacts with a fair amount of meds so it isn't for everyone.
Check your meds just go to safety checker
Some other's to look into:
Use antimicrobial herbs and spices. Before they were used as seasoning, culinary herbs and spices were most likely used for food preservation. Antimicrobial activity of garlic has been repeatedly demonstrated against many species of bacteria, fungi, parasites and viruses. The dose of garlic needed to obtain significant benefit is at least ten grams (about three small cloves) per day. Onion lacks the potency of garlic but can be consumed in much larger quantity, so that its antimicrobial benefits may be equal to those of garlic if consumed regularly. Turmeric relieves intestinal gas by lowering the numbers of gas forming bacteria; it also has anti-fungal activity and has been traditionally used for relieving inflammation. The effective dose is about one gram per day. Ginger, which contains over four hundred chemically active ingredients, has long been used for the treatment of digestive complaints. It protects the intestinal lining against ulceration and has a wide range of actions against intestinal parasites. Sage and rosemary contain the essential oil, eucalyptol, which kills Candida albicans, bacteria, and worms. Oregano contains over thirty biologically active ingredients of which twelve have antibiotic, antiviral, antiparasitic or antifungal effects. Heating at 200 degrees (Fahrenheit) for twenty minutes destroys the antibacterial activity of most of these spices. They should be added to food at the end of cooking, just before being eaten.
Keep in mind some with MS don't like to boost the immune system and garlic is known to do that. We use it like there is no tomorrow. Nothing better than roasted elephant garlic I just chop the top brush with olive oil sprinkle with pepper bake at 350 for 20 minutes or so then remove skin and dust liberally with turmeric and it is great on just about any meat. Also another way is to skin a couple bulbs as well as a dozen pearl onions a dozen mushrooms some red,green yellow or orange pepper and toss in a hot pan greased lightly with olive oil and coated with turmeric and serve over a pasta. Another favorite here.
Remember turmeric should not be on the heat long so add near the end
