| Its the volatile oils that are present in many of the herbs that need to be kept out of sunlight once they are extracted. You should always minimize the amount of sunlight that your jow is subjected to, new or old. The more air, sunlight, and heat that your jow gets, the more it will break it down, regardless how long its been aged.
A tiny bit of light isnt really a big deal as long as it is kept minimal; obviously you cant apply it and shake it pitch black--just use common sense. Keep it out of the light but you dont need to go overboard with this, being silly and applying it only in complete darkness, etc.
The use of tinted bottles can keep almost all of the light out of the bottle and keep your jow safe for carrying around, etc. |
