Dry cistanche deserticola has been stored for eighteen years. Is it still valid? Are there any negative effects when using it?

It doesn't work. It should be stored in a cool and ventilated place for long-term preservation. If it is not well preserved, it may be prone to long hair and mildew in less than 3 years, or it may directly deteriorate. If it is well preserved, it can be preserved for 4 to 5 years.

The active ingredients of fresh dried tablets of Cistanche deserticola are the same as those of traditional tablets of Cistanche deserticola, namely echinacoside, and the content of echinacoside determines the efficacy of Cistanche deserticola tablets. Fresh dried slices were picked from the ground and sliced within 12 hours, which ensured the maximum content of echinacoside and the effect was far better than that of traditional cistanche deserticola slices. Studies have shown that Cistanche deserticola tablets are more suitable for soaking in wine, and can quickly release the effective components of echinacoside contained in Cistanche deserticola tablets.

Extended data

From April to June every year, when Cistanche deserticola is unearthed, it should be excavated in time to ensure the integrity of Cistanche deserticola as much as possible. In order to reduce the damage to the host plants, we should choose the periphery of cistanche deserticola connected with the host to dig a pit to the bottom of cistanche deserticola, cut the upper part 5-8cm from the connection point on the premise of continuously opening the connection point between cistanche deserticola and the host, and then backfill and slightly compact it. This can ensure that Cistanche deserticola is inoculated 1 time, and the stable production period can reach 5-7 years.

Scald or cut off the discolored head of Cistanche deserticola with boiling water, then air-dry it on a clean cement floor or other non-metallic utensils, turn it over 2-3 times a day to prevent mildew, and collect and package it after it is completely dried (water content 10% or less).
