Actually yeah, lime, lemon, cucumber, and daun sirih as fas as I know has anti-bacterial properties that helps fight off bad odor. Lime and lemon can make dandruff go away (personal experience), smell very very fresh but kinda drying. Cucumber and daun sirih is better if wanna have the same effect while keeping the moisture on, but smell.. cucumber-like, haha. Also hibiscus flower and its leaf, and batang kangkung is also good for hair care. And absolutely no side effects, 100% effective and the effect is long lasting buttt it take a lot of effort and time to see the result. Like really really long, 1 year or more. But once you got to it, basically you will be good for life as long as you exercise the routine 1 or twice per week. Fragrance in products actually is not good, that's why some people say opt for fragrance-free stuff, coz fragrance can dries the skin. So safer alternative is using daun pandan or rose tea (the pricier ones without coulouring added). I use green tea leaves left after drinking it to scrub my face and fine coffee powder for my body (coz they are cheap) and what I can say is that, I got wayy better result than using over the counter products. My over sensitive, ezcema skin recover faster now and isn't dry anymore, no more suffering like before. I think it is because natural stuffs are really mild and very gentle on the skin. So yeah it may sounds weird but give it a go if you are interested, it may help.
