Hi swell,
I was thinking about your question about stopping a virus. I've been drinking aloe vera gel drinks as a way to directly suppress viral replication.
Aloe emodin is one of the active ingredients in aloe vera leaves and is highly concentrated in aloe vera gel. Aloe vera gel is know for its therapeutic properties of the skin. But aloe emodin has been shown to inhibit herpes virus (HSV-1, HSV-2, VZV, EBV, CMV) replication and to be virucidal (
RefFRMA,
RefRSRB,
RefKZZR,
RefJKHT,
RefKSWW). Aloe emodin is also inhibits the activity of NF-kB and down-regulates the expression of the MMP-2, JNK and MAPK genes used in collagen breakdown, stress sensing and viral replication (
RefMPSK,
RefLLCS). Aloe emodin reduces blood vessel inflammation by downregulating MMP-2, MMP-9 and VEGF through inhibition of NF-kB (
RefPSSG,
RefMKRN).
ID
50 and ID
90 values of
aloe emodin for inhibiting viruses (
Inactivation of enveloped viruses by anthraquinones extracted from plants). For the HSV-1 ID
50 value, the unit conversion is 1.6 ug/ml = 5.7uM (1 ug/ml = 1/0.279 uM). Herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), varicella-zoster virus (VZV), pseudorabies virus (PSV), influenza virus (INF), adenovirus (AD), and rhinovirus (RH).
It also inhibits the expression of COX-2 and iNOS resulting in a reduction of inflammatory nitric oxide and PGE
2 with equal potency as quercetin (
RefMPMS1). The bioavailability of aloe emodin is ~10% (
RefMPMS2). Aloe emodin is neuroprotective against NMDA-excitotoxicity by upregulating superoxide dimutase (SOD) (
RefHLFT2,
RefHLFT1).
From my understanding, aloe vera juice does not have as much emodin as the gel does. Aloe vera gel can be sourced
here1 or
here2. It should be diluted as 1 Tbs of aloe vera gel per 8oz of water (or other drink). This can be consumed daily 3 times a day. I have already started testing aloe vera gel mixed in a juice with some good results. It clearly crosses the BBB and has positive cognitive effects. I'm thinking that aloe vera gel may be a very effective at stopping POIS. I'll post about my trial later. Below is a commercial aloe vera drink that I have also been drinking. The sugar content is relatively small.
