It's NOT grape seed extract. It's grapefruit seed extract that you want for the infection.i noticed people are getting this confused.

Were you using the maximum strength or the regular strength?
Thanks for your help.

I am replying to my own post since it got no replies in 2 years. I think when people post here, they should make it a point to mention what strength of GSE they are using. There are two strengths...regular and maximum. To use 10 drops of maximum is too much so, I am assuming they are using the regular strength. Please make that distinction since it is misleading for people who are not aware that there are 2 strengths for sale.For clarity, I called "NutriBiotic"...the company that sells both strengths and they told me that the regular strength GSE has directions for taking it internally but a few years back, the FDA had them stop putting a dosage on their Maximum strength bottles and told them that they had to put: "For external use only" on the Maximum strength bottles. But, they used to put "Take 3 drops daily" before they were told not to. So, if you use the Maximum strength, use only 3 drops a day as it is much more potent.

Taking 8 drops would be for the standard strength GSE Grapefruit Seed Extract.Citricidal strength is much more concentrated, apx 82% stronger. Citricidal is 60% grapefruit seed extract (40% vegetable glycerin), while the standard strength is 33% grapefruit seed extract (67% vegetable glycerin).

A direct copy of the exact, historical instructions specifically written for the NutriBiotic Maximum Strength / Citricidal Professional Strength Concentrate (60% active Citricidal, 40% vegetable glycerin) details the specific recommendations before the oral instructions were entirely removed from the label:
1. Oral Use (Internal Wellness)
- Adults: Thoroughly mix 1 to 3 drops into a minimum of 8 ounces of water or juice. Drink 1 to 2 times daily, with or without meals.
- Maximum Limit: The vintage guide noted that under the direction of a healthcare professional, the dose could be SLOWLY advanced (titrated) up to 5 drops maximum per serving, up to 3 times a day.
- Children (Ages 5+): Mix exactly 1 single drop into 8 ounces of juice with stevia or a heavily sweetened beverage to mask the intense bitterness. Do not exceed 1 serving per day.
2. Specialized & Topical Dilutions
Because the old Maximum Strength concentrate contains nearly double the active Citricidal of regular GSE, the vintage topical guides explicitly restricted the drop count to avoid burning the tissues:
- Throat Gargle: Stir 2 to 3 drops into 6 to 8 ounces of warm water. Gargle deeply for 10–20 seconds. Do not swallow.
- Nasal/Sinus Spray: Add only 1 drop to a 1-ounce or 2-ounce nasal sprayer filled with pure saline solution. Shake the bottle intensely for 30 seconds before spraying to ensure complete dispersal.
- Vaginal/Yeast Douche: Mix no more than 2 to 3 drops into 8 ounces of warm, distilled water. Shake or stir thoroughly before use. Apply once daily for a maximum of one week.
- Dental Swish & Water Flossers: Add 1 single drop to 4 ounces of water for an oral rinse. For water-reservoir dental flossers, add 2 drops to a fully filled water reservoir tank.
- Skin & Scalp Wash: Wet your face or hands. Add 1 drop to your palm alongside your liquid facial cleanser or regular shampoo. Mix together in your hands before applying to the face or scalp. Rinse thoroughly with cold water.
3. Historical Emergency Warnings
"CRITICAL: MAXIMUM STRENGTH IS A PURE CONCENTRATE. NEVER USE UNDILUTED. Do not drop directly into the eyes, ears, or nasal passages. If accidental full-strength contact or a severe burning sensation occurs on the skin or mucous membranes, immediately flush with water or rub with vegetable oil / milk for a minimum of 10 minutes. Clean water will dilute the extract, while kitchen fat/oil helps encapsulate the bioflavonoids to stop the stinging."

I take GSE in pill form...obviously it is for internal use and very safe.
