I Bought Some Bar Soap Made With Neem In New

I bought some bar soap made with neem in New Zealand to give as a gift. I assumed that it was appropriate for use as bug repellent. When trying to find some information to supplement the gift, I saw that there were positives and negatives about neem. I tried to find some information, without all the ads to buy neem products. What can you tell me so I can give the information about neem when I give the soap. Thanks.
