Indeed, Yin-care®’s current batch of Herbal Wash shows an “expiration” date of 10.16.23. As you can see, the word expiration is in quotes here. The reason is that we are required to put an “expiration” date on the product; however, it really is supposed to be considered a “Best By” date. We did try to get this printed on the boxes instead of “expiration” but it was not allowed by the Chinese equivalent of our FDA
Factory Level Testing for Efficacy
Yin-care®’s Herbal Wash has been tested for efficacy yearly for ten years and beyond and has been found to still be effective against yeast and non-lacto-bacilli bacteria at the 10% dilution. That would mean that these particular bottles are good at least through 2030+. However, every individual will have a different level of comfortability with this situation. In our clinic, we take time to educate our patients about the the printed dates and our patients are always ok with continuing to purchase and use our product regardless of the date printed. However, this may not be something with which you are comfortable.
Composition of Yin-care®’s Herbal Wash
Recall that Yin-care®’s Herbal Wash is both a water based extraction and an essential oil based extraction of the herbs. Due to the essential oils presence, it acts as a preservative. For example, if you have a bottle of Frankincense Essential Oil, do you consider it expired? It does not really expire because it is not pre-diluted and the same is for the Herbal Wash. Because it is highly concentrated even after 10 years, in the lab studies, it showed that it had NOT reached a form of expiration. Every 3 months lab technicians would check Yin-care®’s Herbal Wash efficacy on a petri dish of bacteria. As stated, it continued to show as effective.
Successful Use of Past – Dated Product
Dr. Hudson has been using it since 1999 – has never had a problem with any product – We have one patient still using bottles form 2002 that work well. The expiration date is something we were forced to put on the bottles. If your patients still have a bottle in their cupboard that expired 10 years ago – it would still do the job. However, we always recommend testing the wash on the inner wrist to be sure that there is no reaction.
The reason we are even suggesting this is for your comfort and continuity of your self-care protocol. We are concerned about our ability to bring in another batch from China considering we have had difficult with Yin-care®’s Supreme Oral Care.
We are working on a more sustainable solution that allows us more control over the product. We will keep you in the loop as that evolves; however, please note that there is a possibility that there would be a few months without a decent supply within date. We are doing our best to avoid this possibility.
Check the Box Upon Check Out!
Due to these factors, we are asking you to check a box upon check out acknowledging that you are aware of the printed “expiration” date and that you are ok with that. We will not allow for product returns related to expiry.
